MG ZS & ZS EV Buyer's Guide UK 2026: Petrol, Electric, Battery Reality & What to Check

Introduction

The MG ZS is one of the UK's great bargain stories of the last decade. Launched in 2017 as a small, affordable SUV from a brand most British buyers associated with sports cars from a previous era, it was dismissed by many observers as too cheap to take seriously. The ZS went on to sell in enormous numbers regardless, and the arrival of the fully electric ZS EV in 2019 — at a time when affordable electric SUVs were essentially non-existent — cemented the car's status as a genuinely disruptive product in the UK market.

By 2026, the used market for both the petrol ZS and the ZS EV is deep and well-supplied. Prices range from under £6,000 for early petrol examples to around £20,000 for recent ZS EV Long Range models. For buyers who understand what they are looking at and what to avoid, this represents outstanding value. But there are traps: the ZS EV's early battery and charging limitations are frequently misunderstood, the 7-year warranty that is such a prominent part of MG's marketing comes with meaningful conditions that can catch used buyers off guard, and interior quality and refinement lag noticeably behind European and Japanese rivals at the same price points.

This guide covers everything you need to know before buying a used MG ZS or ZS EV in the UK in 2026: which engines to choose, what the ZS EV's range really looks like in British winter conditions, what the warranty does and does not cover for a second-hand buyer, the common faults to inspect for, and fair market prices across the model range.

A Brief History of the MG ZS

Original MG ZS (2017–2021)

The first-generation MG ZS arrived in UK showrooms in late 2017, positioned as a budget alternative to the likes of the Nissan Juke, Renault Captur, and Peugeot 2008. Built in China for SAIC Motor — the state-backed group that owns the MG brand — and sold through a growing UK dealer network, it was priced substantially below mainstream rivals of equivalent size.

The original car was offered with two petrol engines: a 1.5-litre naturally aspirated unit producing around 106bhp, and a 1.0-litre turbocharged three-cylinder producing approximately 111bhp. Both could be specified with a six-speed manual gearbox; the 1.5 NA was also available with a six-speed automatic. Neither powertrain was a match for class rivals on refinement or performance, but both were adequate for everyday UK driving, and the car undercut rival pricing significantly enough to attract buyers who prioritised value over driving experience.

The interior reflected the budget positioning. Plastics were hard and scratchy in places, the infotainment system was functional but slow by contemporary standards, and road and wind noise intrusion at motorway speeds was higher than buyers familiar with mainstream rivals would expect. The upside: the ZS offered genuinely good interior space for its class, a large boot by the standards of small SUVs, and reasonably comprehensive equipment at each trim level.

2021 Facelift

MG significantly updated the ZS in 2021 with a restyled exterior that gave the car a more assertive, SUV-like face — replacing the somewhat anonymous original design with a bolder grille and slimmer headlamps. The interior also received updates including a redesigned centre console, an improved infotainment display, and revised switchgear. Build quality improved meaningfully over the first-generation car, though it remained well behind premium European rivals.

The facelift also brought revised powertrain options, including the availability of a dual-clutch automatic transmission on certain variants, and updated trim-level naming. For used buyers, the 2021 facelift represents a meaningful improvement over earlier examples and is generally the recommended starting point when shopping.

ZS EV Timeline

MG launched the fully electric ZS EV in the UK in December 2019, powered by a single front motor and a 44.5kWh battery offering an official WLTP range of 163 miles. It was priced at around £28,000 new before the government's Plug-in Car Grant, making it one of the most affordable electric SUVs on the UK market at the time.

In 2021, MG significantly updated the ZS EV alongside the petrol facelift. The original 44.5kWh battery was replaced with two new options: a 51kWh Standard Range unit offering 198 miles WLTP, and a 72.6kWh Long Range battery offering 273 miles WLTP. Both were paired with a more powerful motor producing 154bhp (Long Range) or 130kW/174bhp (Standard Range), and DC rapid-charging speed increased from a maximum of 50kW on the original car to 76kW on facelifted models. These are meaningful improvements across the board, and the pre- and post-facelift ZS EVs are sufficiently different that they deserve to be treated as distinct cars when buying used.

Petrol or Electric — Which MG ZS?

The fundamental buying decision. Here is how the two versions compare across the factors that matter most to used buyers.

The petrol ZS makes most sense for buyers who do not have home charging, cover high annual mileages on motorways, or need a first car with lower insurance costs. The ZS EV makes sense for buyers who can charge at home overnight, do mostly local and commuting miles, and want the lowest possible running costs — provided they choose the right battery size. The Long Range ZS EV in particular is a compelling used buy; the Standard Range and original 44.5kWh are more compromised by UK real-world range expectations.

Petrol Engine Options

1.5-Litre Naturally Aspirated

The base petrol option for much of the ZS's production life. A conventional, four-cylinder naturally aspirated unit producing around 106bhp and 150Nm of torque. It is not a refined engine — the lack of forced induction means it requires revving to produce usable power, resulting in more noise and less flexibility than the turbocharged alternative.

Real-world fuel economy on UK roads is typically 32–36mpg in mixed driving, dropping to the high 20s on motorway runs at 70mph. For a car of this size and price, that is unremarkable but not disastrous. Servicing is straightforward and cheap, with few known catastrophic failure modes beyond what you would expect from any high-mileage naturally aspirated engine.

The six-speed automatic version is the more popular choice in the used market. The automatic calibration is generally smooth, though it can hunt for gears on inclines and occasionally feels slow to respond to overtaking demands. The manual gearbox has a notchy, imprecise action that some owners find grating on long motorway journeys.

1.0-Litre Turbocharged

The more desirable petrol option, though the difference in power (approximately 111bhp) versus the 1.5 NA is modest. The real benefit of the 1.0T is its turbocharged delivery: better low-down torque, a more flexible power band, and improved real-world fuel economy, typically 37–42mpg on mixed driving for careful drivers.

The three-cylinder layout does produce some vibration at idle and low revs — not unusual for a unit of this configuration — and road noise remains a more significant issue than the engine character itself. The 1.0T is the better choice between the two petrol options if one is available at a similar price; avoid examples that appear to have been neglected, as the turbocharger can be sensitive to oil change intervals.

A note on emissions: the 2017–2021 petrol ZS used a Euro 6 engine, which means it is compliant with current ULEZ requirements in London and most Clean Air Zones across the UK. If you are buying for use in a city with emission zone charges, confirm the exact Euro standard of the specific car via its V5C before purchasing — earlier or grey-import examples may differ.

MG ZS EV: Battery and Range Reality

This section matters more for used buyers than almost anything else. The ZS EV has been through two meaningfully different generations of battery technology, and conflating them causes considerable confusion in the used market.

Original 44.5kWh Battery (2019–2021)

The first ZS EV used a 44.5kWh lithium-ion battery and a single front motor producing 141bhp. MG quoted a WLTP range of 163 miles, which was honest for combined use — but motorway driving at 70mph, particularly in winter, produces considerably less. Real-world winter motorway range on early ZS EVs is consistently reported at around 100–120 miles in cold conditions, with warmer summer mixed-route driving returning closer to 130–145 miles. These are not figures that make the original ZS EV suitable as a sole car for anyone with significant motorway mileage requirements.

DC rapid charging on this car is limited to a maximum of 50kW CCS. That means a charge from 10–80% takes approximately 40 minutes at a fast charger — slower than many rivals, and a real-world inconvenience on long journeys. AC home charging is capped at 6.6kW, giving a full charge from flat overnight in around seven to eight hours on a 7kW wall box (it will charge at 6.6kW regardless of the wall box's rated output).

For buyers on a tight budget looking at £6,000–£9,000 early ZS EV examples, this is the car you will encounter. It is genuinely practical for urban and short-distance commuting use — and at the prices these cars now command, the value case is understandable — but enter with realistic expectations about range and charging speed. At motorway speeds in January, 100 miles is a realistic working range.

2021 Onwards: Standard Range and Long Range

The facelifted ZS EV is a substantially better car than its predecessor in almost every measurable respect. The Long Range in particular — with approximately 230–255 miles of real-world mixed driving range and 170–200 miles on a cold motorway day — is genuinely usable as a sole car for most UK drivers who have home charging. That winter motorway figure of 170–200 miles comfortably covers London to Manchester with a single stop, for example.

The Standard Range (51kWh) sits in an awkward middle ground: improved over the original but not dramatically more capable in winter conditions where it still returns closer to 120–145 miles at speed. For buyers who do primarily urban and suburban driving, it is fine. For those expecting genuine long-distance capability, the Long Range is worth the premium.

Winter Range and Real-World Expectations

All electric vehicles suffer range reduction in cold weather — cabin heating draws heavily from the battery, and lithium-ion chemistry is less efficient at low temperatures. The ZS EV is no exception, and the standard range model is particularly affected given its smaller pack.

MG fitted a heat pump to the ZS EV from the 2021 facelift onwards, significantly improving cold-weather efficiency compared to the original car which relied on a resistance heater. This is not a trivial difference: a heat pump can reduce the energy consumed by cabin heating by 30–50% compared to a resistance element, which translates directly into longer winter range. If you are comparing a pre-2021 car (no heat pump) with a post-2021 car (heat pump standard), this is a meaningful hidden advantage of the newer vehicle that is rarely highlighted in used car listings.

Charging the ZS EV

Home Charging

The vast majority of ZS EV running costs are determined by home charging. A 7kW AC wall box — now available for £500–£900 installed through OZEV-approved installers — is the optimum home charging solution. The ZS EV (post-2021) accepts up to 7.4kW AC, so a 7kW wall box delivers a near-full charge overnight in most cases. On a standard variable tariff at approximately 25–28p per kWh in mid-2026, home charging costs around 3.5–5p per mile for the Long Range model.

On an economy-style or smart tariff with cheap overnight rates (often available from 7–15p per kWh), the per-mile cost falls to 2–3p — making the ZS EV genuinely economical to run for high-mileage commuters.

Public DC Rapid Charging

The ZS EV uses the CCS (Combined Charging System) connector standard for DC rapid charging — the same connector used by virtually all non-Tesla EVs sold in the UK. This means compatibility with bp pulse, Pod Point, Osprey, Gridserve, and similar networks. The maximum charging speed of 76kW on post-2021 cars is adequate but not fast by 2026 standards, where many rival EVs charge at 100–150kW or above.

At a 76kW-capable charger, the Long Range ZS EV adds roughly 100 miles of range in 20–25 minutes (charging from around 20% to 80%). This is workable for occasional long-distance use but makes the ZS EV a less practical choice than faster-charging rivals if you regularly cover 200+ miles in a single journey without home charging access.

The original pre-2021 ZS EV's 50kW CCS maximum is a genuine limitation. At a 50kW charger, the 0–80% charge takes around 40 minutes — which is not terrible in absolute terms but does mean the car is bypassed by faster networks that do not step down to 50kW when occupied. Many newer rapid chargers are designed primarily for 100kW+ vehicles.

One Important Note on Charging Compatibility

The ZS EV does not have access to Tesla's Supercharger network (which requires either a Tesla or a car with a Supercharger-compatible account). For long UK trips, ZS EV owners rely on the public CCS network. Coverage on motorways has improved significantly since 2019, but reliability and queue management at busy sites remains more variable than the Tesla Supercharger experience. Factor this into your ownership planning, particularly if you regularly travel routes away from major motorway corridors.

MG's 7-Year Warranty — What It Actually Means for Used Buyers

MG's seven-year, 80,000-mile manufacturer warranty is one of the brand's most effective marketing messages, and for good reason: it is genuinely longer than most mainstream competitors offer. Understanding what it covers and, critically, what conditions must be met is essential for any used buyer.

What Transfers to You

The warranty is vehicle-attached, not owner-attached. It transfers automatically to each subsequent owner, as many times as necessary, for as long as the seven-year period and 80,000-mile limit have not been reached. There is no mileage limit in year one, after which the 80,000-mile cap applies. A 2021-registered ZS EV still has warranty coverage until 2028 (from first registration) provided it has not exceeded 80,000 miles.

For the high-voltage battery specifically, MG offers an eight-year, 100,000-mile warranty covering degradation below 70% of original capacity — mirroring the terms of most mainstream EV manufacturers. This battery warranty also transfers to used buyers.

The Conditions You Must Meet

Here is where used buyers must pay close attention:

Service schedule compliance. To maintain warranty validity, each service must be carried out within 1,000 miles or 28 days of the recommended interval. Services must use MG-approved fluids and parts. If there is a gap in the car's service history — or if the previous owner used a non-approved independent garage without the correct documentation — the warranty may be affected.

No modifications. Any modification to the vehicle voids warranty coverage across the entire car, not just the modified component. This includes modifications made by a previous owner. Aftermarket accessories not fitted by an approved MG dealer, third-party software installations, and non-standard wheels can all affect warranty status.

Anti-perforation warranty conditions. The separate seven-year anti-perforation (rust-through) warranty requires an annual bodywork inspection by an MG dealer or approved repairer to remain valid. Many private sellers and even some dealers are unaware of this condition; check whether the car has had these inspections if bodywork warranty is important to you.

The Practical Reality for Used Buyers

For a 2021-registered ZS EV with a full documented MG dealer service history, the remaining warranty is a meaningful asset worth several hundred pounds in peace of mind — particularly on the drivetrain and battery. For a car with a patchy service history, modifications, or gaps in documentation, treat the warranty as a bonus rather than a certainty. Always ask to see the full service history, confirm stamps are from authorised MG dealers or documented by them, and check the outstanding warranty period against the VIN via MG Motor UK's website before purchasing.

Trim Levels Explained

The MG ZS and ZS EV have used two distinct naming conventions across their production runs, which can cause confusion in used listings.

2017–2021 Trim Naming: Explore, Excite, Exclusive

Explore was the entry-level trim on early petrol models. It typically included 16-inch alloy wheels, a touchscreen infotainment system with Apple CarPlay and Android Auto, rear parking sensors, and climate control — a reasonable base specification. However, it omitted features such as a rear-view camera and leather upholstery that many buyers expect.

Excite was the mid-range trim, adding 17-inch alloy wheels, a rear-view camera, and upgraded interior detailing. This is the most commonly found trim in the used market for early ZS models and represents reasonable all-round specification.

Exclusive was the top trim, adding leather upholstery, an electric driver's seat, front parking sensors, and a panoramic sunroof on some variants. Exclusive examples command a premium in the used market but are the most complete specification available on pre-facelift cars.

On early ZS EV models (2019–2020), the trim structure was broadly similar: Excite and Exclusive trims were the main options, with the Exclusive adding the leather and panoramic roof.

2021 Onwards: SE, Trophy, Trophy Connect

From the 2021 facelift, MG moved to revised naming:

SE — the entry-level designation on facelifted petrol and the base ZS EV (51kWh). Includes the larger touchscreen, Apple CarPlay, Android Auto, rear camera, and alloy wheels. A solid base but omits heated seats and some safety technology.

Trophy — the mid-to-top trim that most buyers should target. Adds heated front seats, a larger infotainment display (on some variants), upgraded alloy wheel designs, and enhanced safety suite including blind-spot monitoring and rear cross-traffic alert. On the ZS EV, Trophy is available on both Standard Range and Long Range battery options.

Trophy Connect — the top-of-range on ZS EV models, adding connected services, an enhanced audio system, and additional driver assistance features. Relatively rare in the used market; a low-mileage Trophy is usually better value than a higher-mileage Trophy Connect.

Which trim to buy? For the petrol ZS, Excite (pre-facelift) or Trophy (post-facelift) offer the best balance of specification and value. For the ZS EV, prioritise battery size over trim level: a Long Range SE is almost always a better purchase than a Standard Range Trophy.

Common Faults and Known Issues

The MG ZS and ZS EV have broadly acceptable reliability records, particularly on the battery and drivetrain of the electric versions. However, several recurring fault patterns are well-documented by UK owners and worth investigating at any viewing.

Infotainment Lag, Freezing, and Reboots

This is the most frequently cited complaint across the entire ZS range, petrol and electric. The infotainment system — particularly on pre-facelift cars with the older software stack — is prone to sluggish response, screen freezing, and spontaneous reboots. The system typically recovers without intervention, but mid-journey reboots can disable Apple CarPlay, navigation, and climate display simultaneously for 30–60 seconds.

The facelifted cars from 2021 onwards use improved hardware and more recent software, and the frequency of these complaints reduces markedly. OTA (over-the-air) software updates have addressed some specific issues on both generations. At any viewing, spend at least 10 minutes using the infotainment system including navigation, media, and phone connectivity before dismissing it.

MG dealers can apply software updates under warranty to address known infotainment issues. If you buy a pre-facelift car with an outstanding warranty and experience software problems, book a dealer appointment promptly.

Road Noise and Refinement

The ZS — in both petrol and electric forms — is not a refined motorway car. Road noise intrusion at speeds above 60mph is noticeably higher than mainstream European or Japanese rivals at equivalent price points. The pre-facelift car is particularly affected; the 2021 update brought some improvement through revised door and windscreen sealing, but it does not transform the ZS into a quiet motorway cruiser.

For primarily urban drivers this is a non-issue. For buyers who regularly cruise at 70mph on dual carriageways, it is worth factoring into the decision — particularly given that the ZS EV lacks any combustion noise to mask road noise below around 60mph, making the tyre roar more prominent than in a petrol car.

Interior Plastics and Build Quality

The ZS interior uses hard, hollow-sounding plastics on the door cards, dashboard lower sections, and centre console that were below class standards in 2017 and have not improved significantly since. Rattles and squeaks can develop over time, particularly around the dashboard and A-pillar trim on higher-mileage examples. These are largely cosmetic and do not affect reliability, but they are a persistent reminder that the ZS's value proposition depends on looking past interior ambience.

Check at viewing that all interior trim pieces are firmly attached, that no dashboard rattles are audible at idle, and that the heated seat switches (where fitted) function correctly.

12V Battery Failures (ZS EV)

Like all electric vehicles, the ZS EV uses a conventional 12V auxiliary battery alongside its high-voltage main pack. This 12V battery powers the car's computers, locks, lights, and ancillary systems. Failure of the 12V battery — which can occur from around three to four years of age on early cars — can render the ZS EV completely non-functional: unable to open, unable to charge, screens dark.

UK ZS EV owners on forums report 12V battery failures at rates higher than those typically seen in mainstream petrol cars. The battery itself is not expensive to replace (approximately £80–£150 for parts, fitting within a warranty claim if applicable), but unexpected failure is stressful. Ask any seller of a 2019–2022 ZS EV whether the 12V battery has been replaced. If not, and the car is more than four years old, budget to have it done soon after purchase.

Brake Feel on the ZS EV

The ZS EV uses regenerative braking to recover energy during deceleration, which in most driving conditions means the physical brake discs and pads are used relatively rarely. This is efficient and reduces servicing costs — but it creates two related issues.

First, brake disc corrosion: because the mechanical brakes are rarely used heavily, the discs can develop surface rust, particularly on cars used primarily in wet urban conditions. This is usually superficial and clears after a few firm applications, but heavy lipping on the disc edges or significant pitting warrants attention.

Second, brake feel: the ZS EV uses blended braking (a mix of regenerative and physical braking) that some drivers find grabby or inconsistent at low speeds, particularly when transitioning from regenerative to friction braking in the final metres before a stop. This is a characteristic of the system design rather than a fault, but it catches some drivers off guard initially and is worth being aware of during the test drive.

TPMS and Minor Electrical Faults

A steady stream of ZS and ZS EV owners report intermittent TPMS (tyre pressure monitoring system) warnings that appear even when tyre pressures are correct. The system can trigger false alerts after tyre rotation, in very cold weather, or following a wheel wash. Most warnings self-resolve without intervention, but persistent TPMS fault messages with no identifiable pressure issue may indicate a faulty sensor (replacement sensors cost approximately £30–£60 each).

More broadly, minor electrical gremlins — random warning lights that clear on restart, occasional loss of connectivity features, and intermittent rear camera hesitation — are reported more often on ZS models than on many European rivals. Most resolve themselves or require only a software update under warranty, but it is worth checking owner forums before viewing any specific car.

Suspension Wear (Petrol ZS)

The petrol ZS has reported front suspension wear — particularly the front lower arm bushes and ball joints — on higher-mileage examples, particularly pre-facelift cars with more than 60,000 miles. Symptoms include a tramline feeling over road undulations, minor clonking over low-speed speed bumps, and uneven tyre wear (cupping or scalloping). At viewing, drive slowly over a speed bump and listen for clonking; check tyre wear across the full tread width. Budget £150–£300 for bush replacement if signs of wear are present.

Running Costs

Fuel Economy (Petrol ZS)

Real-world fuel economy on the petrol ZS varies considerably by engine choice and driving style:

• 1.5 NA (manual or automatic): 30–36mpg in mixed driving; high 20s on motorways at 70mph
• 1.0T (manual or automatic): 36–42mpg in careful mixed driving; low 30s motorway

At current UK petrol prices of approximately £1.42–£1.50 per litre (July 2026), the 1.0T ZS costs roughly 9–10p per mile in fuel. The 1.5 NA comes out at approximately 11–13p per mile. For 10,000 miles per year, the difference amounts to roughly £200–£400 annually — meaningful but not dramatic.

Charging Costs (ZS EV)

On a standard variable home tariff at approximately 26–28p per kWh:

• Long Range (72.6kWh): approximately 4–5p per mile
• Standard Range (51kWh): approximately 3.5–4.5p per mile

On a smart tariff with overnight rates around 7–12p per kWh:

• Long Range: approximately 1.5–2.5p per mile

Public rapid charging at CCS networks varies from around 50–85p per kWh depending on provider, time of day, and membership status. At 70p per kWh — a representative mid-market rate — the Long Range ZS EV costs approximately 9–11p per mile when charged publicly, eroding much of the EV cost advantage over petrol. Home charging access is therefore not merely convenient — for the ZS EV's running cost case to hold, it is essential.

Road Tax (VED)

Petrol ZS (registered 2017–2024): Standard VED rates based on CO2 emissions. Most ZS petrol models fall into the £195 per year rate under the post-April 2017 first-year then flat-rate system. The 1.0T typically emits 128–138g/km CO2, placing it in the band that attracts standard flat-rate VED from year two onwards.

ZS EV (registered before 1 April 2025): From 1 April 2025, electric vehicles lost their VED exemption. ZS EVs registered between 2019 and March 2025 now pay the standard flat-rate of £195 per year — the same as a petrol equivalent of the same era.

ZS EV (registered from 1 April 2025 onwards): £10 in year one, then £195 from year two. New ZS EVs priced above £40,000 when new would also attract the expensive car supplement (£425/year from years two to six), though most ZS EV trim levels were priced below this threshold.

Servicing

The petrol ZS follows a standard oil-and-filter service schedule. MG recommends annual services or 10,000-mile intervals, with alternating minor and major services. Independent garages familiar with Chinese-market vehicles can service the ZS at competitive rates; franchised MG dealer servicing costs are broadly in line with mainstream rivals. Budget approximately £120–£200 for a minor service and £250–£400 for a major service including air filter, pollen filter, and brake fluid replacement.

The ZS EV has lower servicing costs due to the absence of engine oil, timing belt, spark plugs, and exhaust components. MG recommends annual inspections covering brake fluid, tyre condition, high-voltage system safety checks, and 12V battery. Budget approximately £100–£180 per year for EV servicing at an MG dealer or independent EV specialist.

Insurance Groups

The significant jump in insurance group between the petrol and electric variants reflects the higher repair costs and parts prices associated with EVs generally. A 30-year-old driver in a mid-risk postcode can typically expect annual comprehensive premiums of around £600–£900 for a petrol ZS; for the ZS EV Long Range Trophy, premiums in the range of £900–£1,400 are common, rising substantially for younger drivers. Get insurance quotes before committing to a specific variant, particularly if the EV insurance group will stretch your budget.

What to Check Before Buying

Before the Viewing

• Run a full vehicle history check to confirm the car has no outstanding finance, write-off category markers, mileage discrepancies, or flood damage flags. The ZS EV in particular is a popular finance car — PCP and HP agreements remain secured against the vehicle's V5C, and you can inherit liability for outstanding debt if you buy without checking. On carhealth.co.uk you can run an instant history check against any registration plate before you travel to view.
• Check the DVLA's free MOT history service for the registration plate. Look for recurring advisories (particularly around suspension, tyres, or brake efficiency) and any failures that suggest issues with hidden components.
• Confirm the remaining MG warranty period using the VIN via MG Motor UK's website or by contacting a franchised dealer.
• Verify the full service history is available and that stamps are from authorised MG dealers or documented by them.

At the Viewing

• Check the exterior carefully under daylight for panel alignment inconsistencies, especially around the boot lid, bonnet, and front wings. Some early ZS models showed variable panel gap consistency from the factory.
• Inspect the tyres for even tread depth across the full width. Uneven or cupped wear can indicate suspension geometry issues requiring attention.
• On the ZS EV, check the brake discs (visible through the wheel spokes) for excessive lipping or heavy surface corrosion — some surface rust on an EV is normal, but significant lipping warrants further investigation.
• Open and close all doors, the boot, and the bonnet. Listen for rattles when driving over a rough surface.
• Check that the infotainment system starts without a lengthy delay, connects to Bluetooth, and that Apple CarPlay or Android Auto functions correctly.
• Look under the bonnet for any signs of oil leaks (petrol), coolant residue, or corrosion on battery connections (visible on some ZS EV high-voltage connector housings).

During the Test Drive

Petrol ZS:

• Drive at motorway speeds on a dual carriageway for at least 10 minutes and note the road noise level. Some noise is normal; excessive roaring from the tyres suggests worn tyres or degraded door seals.
• Test the gearbox — manual models should have a clean, positive shift action; automatics should not hunt for gears or slip when pulling away from rest.
• Check that the engine pulls cleanly through the rev range without hesitation. Hesitation on the 1.0T at low revs can indicate a failing turbocharger or intake issue.

ZS EV:

• Check the available range shown on the battery gauge at the current state of charge. Compare this figure against expected real-world range at the battery percentage shown — this gives a rough indication of battery health.
• Test the regenerative braking: release the accelerator at moderate speed and note whether deceleration feels consistent and predictable.
• Drive over a speed bump slowly and listen for any suspension clonking, which is more audible in the quiet cabin of an EV than in a petrol car.
• Run the climate system for 10 minutes on a moderate heating or cooling setting and check it functions without fault codes.
• Test the charging port opens freely and that a public CCS cable (if you can borrow one) connects and latches correctly.

Typical UK Used Prices (July 2026)

Prices reflect broad market ranges for privately advertised and dealer-listed examples in reasonable condition. Condition, service history, mileage, and geographic location all influence individual asking prices. These are approximate guides only.

Petrol MG ZS (2017–2023)

MG ZS EV

The steepest depreciation curve has already passed on the original ZS EV — early cars lost value rapidly as the 2021 facelift arrived with meaningfully better range and charging. A 2019 or 2020 example in the £6,500–£9,000 range is now stable in value and represents an affordable urban EV for buyers who understand the range limitations. The sweet spot for used buyers wanting genuine long-range capability is a 2021–2022 Long Range Trophy or Trophy Connect in the £11,000–£16,000 range: these cars offer close to 250 miles of real-world mixed range, heat pump heating, and updated infotainment, with several years of warranty typically remaining.

Alternatives to Consider

The MG ZS and ZS EV sit in a competitive segment. Before committing, it is worth considering these alternatives.

Kia Stonic / Hyundai Kona (petrol, pre-facelift) — Both Korean crossovers offer better refinement, stronger dealer networks, and class-leading reliability records. Used prices are typically £1,500–£4,000 higher than equivalent ZS examples, which reflects the quality differential honestly. For buyers who prioritise peace of mind over bargain pricing, both are worth the stretch.

Hyundai Kona Electric / Kia e-Niro — The Kona Electric (2018 generation, 64kWh) offers comparable real-world range to the ZS EV Long Range with better driving dynamics and more established service support. Used prices are typically higher than the ZS EV Long Range. The Kia e-Niro offers an exceptionally large battery and real-world range that puts the ZS EV in the shade, though early examples are now approaching ten years old and prices reflect this.

Nissan Leaf (2018+) — A more refined and polished driving experience than the ZS EV with a well-established dealer and independent service network across the UK. The 40kWh Leaf has comparable range to the original ZS EV; the 62kWh e+ model surpasses it significantly. The Leaf does not support CCS on most UK examples (it uses CHAdeMO), which limits rapid-charging network access considerably compared to the ZS EV — this is a significant practical disadvantage in 2026 as CHAdeMO infrastructure continues to contract.

MG4 (2022+) — MG's newer, more modern electric hatchback. The MG4 is a significantly better car to drive than the ZS EV, with a rear-wheel-drive layout, improved chassis dynamics, and sharper styling. Used prices for early MG4s are now competitive with the ZS EV Long Range. For EV buyers not specifically requiring an SUV body style, the MG4 is worth serious consideration.

Dacia Duster (petrol) — If the petrol ZS appeals purely for its value, the Duster deserves comparison. Slightly less style-conscious but genuinely excellent value, with better real-world reliability scores from owner surveys, a larger ground clearance, and available four-wheel drive on certain variants. A strong alternative for rural buyers who want affordability above all else.

Verdict and Buying Advice

The MG ZS in petrol form is what it has always been: a pragmatic, affordable choice for buyers who want a small SUV without paying small-SUV prices. It is not the most refined, the most exciting, or the most reliable car in its class, but at the prices now available in the used market, it delivers honest, practical transportation with a residual manufacturer warranty that most rivals cannot match. Stick to 1.0T-powered facelift examples from 2021 onwards for the best balance of economy and drivability, and prioritise documented service history above any other consideration.

The ZS EV story is more nuanced and ultimately more compelling. The original 44.5kWh car was a product of its time — genuinely affordable but severely constrained by range and charging speed. The 2021-onwards Long Range is a fundamentally different proposition: 230–255 miles of real-world mixed range, heat pump heating, 76kW DC charging, and a price point in the used market that no direct European rival can come close to matching. For a used buyer with home charging who does primarily commuting and local driving with occasional longer trips, the Long Range ZS EV at £10,500–£16,000 is arguably the best-value used electric SUV in the UK right now.

The caveats are real: interior quality, refinement, and software stability are below the standard of European and Korean rivals; the charging speed ceiling means long motorway journeys require more planning than in a faster-charging car; and the 7-year warranty — while genuinely valuable — comes with service and inspection conditions that must be actively maintained. None of these is a dealbreaker, but buyers entering the MG ecosystem should do so with open eyes rather than expecting a European-quality product at Chinese pricing. On its own terms, the ZS EV Long Range is a remarkable achievement at its current used car prices.

Before any purchase, run a vehicle history check to confirm the car carries no outstanding finance, category-branded write-off status, or mileage discrepancy. The ZS EV is popular in the fleet and PCP market, and finance remains secured against the V5C; buying blind without a history check is a risk not worth taking at any price.
