Ranked #67 car in the UK · Hatchback (EV) · 9,320 units sold last year
The MG MG4 is one of the UK's more popular hatchback (ev) choices, ranked #67 by registrations. The figures below are estimated from segment benchmarks and, where available, real DVSA MOT data — a fully researched profile is still to come.
Estimated profile — the figures on this page are modelled from segment averages and real DVSA MOT data rather than a fully researched, hand-checked profile. Treat them as a guide, not gospel.

How a 2023-registration MG MG4 loses value over time.
Based on the 2023 car with 23,400 miles you entered above — worth about £15,400 today — here is the cost of owning it for the next 3 years, at roughly 7,800 miles a year.

Best age to buy — around 2 years
A 2-year-old example loses roughly £3,600 a year — under half the £10,150 a one-year-old sheds. The steepest drop is behind it.
Assumes roughly £1.45/L fuel (£0.28/kWh for EVs), typical-driver insurance and manufacturer service intervals. A guide for comparison — your own costs will vary.
Where this car ranks against the 330 vehicles in our index — higher is better.
Percentile rank across our full index. A measure is shown only where the data spreads meaningfully across the index.
How the available versions compare on price, running cost, and the headaches each tends to develop.
If your daily driving is short and 200-ish miles of range is enough, this is the cheapest credible used EV in the UK. Insurance and running costs are low.
Watch for
The most-used MG4 trim on the used market. The Trophy adds genuinely useful kit (heated seats, 360 camera) for around £3k — the SE is the value pick if you don't care about those.
Watch for
Extended Range buys real range; XPower buys real pace. Both are niche choices — most MG4 buyers want value, and these two trims weaken that argument. Look at Tesla Model 3 / Polestar 2 used at this money.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.
Adjust the annual mileage to match how you'll actually use the car. Insurance is what you selected above (age 33-39, typical risk, 3 yrs NCB).

"Parts low/medium/high" indicates how easy the replacement part is to source — discontinued or specialist parts mean longer workshop time and bigger bills.

Factory options ranked by how much of their original cost they recover at resale. Anything above 70% return tends to make money back; below 40% is paying for your own enjoyment.
| Option | New cost | Added used value | Return |
|---|---|---|---|
Tow bar (factory-fit) Niche, but the buyers who want one will pay for it. | £650 | £450 | 69% |
Parking sensors & reversing camera Near-expected now — its absence costs more than its presence returns. | £500 | £300 | 60% |
Heat pump Genuinely useful in winter; buyers increasingly look for it. | £1,000 | £450 | 45% |
Heated seats / cold-weather pack | £450 | £200 | 44% |
Faster on-board AC charger | £800 | £300 | 38% |
Metallic or premium paint Almost universal — an unusual colour is the bigger resale risk. | £600 | £200 | 33% |
Panoramic / opening roof | £1,100 | £350 | 32% |
Larger alloy wheels | £700 | £200 | 29% |
Euro NCAP's independent crash-test rating for the MG MG4, from its 2022 assessment.
The passenger compartment of the MG 4 Electric remained stable in the frontal offset test.
Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014.

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Around average
Theft risk is around the UK average. Like most modern cars it has keyless entry, so relay theft is the method to guard against.
Parts theft
Lower
As an electric car it has no catalytic converter, so the most common parts-theft vector doesn't apply.
Worth doing
Whether driving a MG MG4 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Battery-electric — exempt everywhere. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Battery-electric — exempt everywhere. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Battery-electric — exempt everywhere. |
| Glasgow | City centre | — | Likely exempt Battery-electric — exempt everywhere. |
| Edinburgh | City centre | — | Likely exempt Battery-electric — exempt everywhere. |
| Aberdeen | City centre | — | Likely exempt Battery-electric — exempt everywhere. |
| Dundee | City centre | — | Likely exempt Battery-electric — exempt everywhere. |

How well-supported MG is across the UK — a practical read on how easy servicing, parts and warranty work will be to find.
Franchised UK dealers
~150
Large network
Value mass-market
Network size relative to the UK's largest (MG is 3.3% of all franchised outlets)
Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.
