Ranked #200 car in the UK · Hatchback · 1,060 units sold last year
The MG3 has long been one of the cheapest ways into a new supermini, and the latest (2024 on) car is a big step up as the MG3 Hybrid+ full hybrid - genuinely frugal and far more modern than before. The older (2018-2023) MG3 is a basic but extremely cheap used petrol supermini. Either way, the long MG warranty is part of the appeal. Cross-shop the Dacia Sandero, Kia Picanto and used superminis.
How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

The cheapest new hybrid in the UK. Undercuts Toyota Yaris Hybrid by ~£5k. 7-year MG warranty closes the deal. Surprisingly quick (8.0s 0-62) and properly efficient. The MG3 is the budget-hybrid story of 2024.

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).

Euro NCAP's independent crash-test rating for the MG MG3, from its 2025 assessment.
The passenger compartment of the MG 3 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. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.
Not enough first-MOT data yet. This measure needs cars registered from 2020 that have reached their first MOT at three years old; too few have so far for a figure worth publishing.
Not enough first-MOT data yet — no score. A car needs 100 first MOTs from 2020 registrations onward before this can be measured.
MOT outlook
Insufficient MOT history at this car's reference age — too few tests to compute a reliable percentile.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the MG MG3, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

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
Higher
Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.
Worth doing
Whether driving a MG MG3 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 Hybrid petrol engines from 2006 meet Euro 4. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Glasgow | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Edinburgh | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Aberdeen | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |
| Dundee | City centre | — | Likely exempt Hybrid petrol engines from 2006 meet Euro 4. |

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.
These are segment estimates, not manufacturer figures. 296 of 325 catalogued cars share one of 14 identical dimension sets, so they describe a class rather than this particular car. Sourced figures replace them model by model.
