## Why this model

⚠️ Limited UK data — The MG4 only arrived in the UK in 2022, so we have fewer MOT tests and less resale history than established models. However, the MG4 is a fantastic choice if you're looking for an affordable, practical, and fun-to-drive electric car. It offers a great balance of range, performance, and features for the price. It's also backed by a generous 7-year/80,000-mile warranty, which gives excellent peace of mind for a used EV. Its 5-star Euro NCAP safety rating is another big plus. MG has a growing presence in Europe and globally, which bodes well for parts and service network growth.

## What you should pay

The used EV market has seen significant price adjustments, making cars like the MG4 incredibly good value right now. A 2022 MG4 SE Long Range with around 20,000-30,000 miles should be available for around £12,000. This is a sharp drop from its new price, meaning you're getting a lot of car for your money. The market is still softening slightly, but the MG4's competitive pricing makes it an attractive option compared to rivals.

## Which trim to buy

The SE Long Range trim hits the sweet spot. It offers a very respectable 270 miles of WLTP range (compared to 217 for the standard SE) and a more powerful 203hp motor, without the significant price jump of the Trophy Long Range. You get all the essential features like a 10.25-inch infotainment screen, rear parking sensors, and adaptive cruise control, making it excellent value for money.

## What to check before you buy

- While generally reliable, check for typical EV issues like charging port functionality, battery health (though liquid-cooled, always good to check for any unusual range drops), and software glitches. Some early MG4s had minor infotainment bugs, but these are often resolved with updates. Also, check for even tyre wear, as EVs can be heavy on tyres.

## Running costs

Running an MG4 is very cheap, especially if you can charge at home on a smart EV tariff. At a standard home rate (24.5p/kWh), it'll cost you about 7.1p/mile, or around £710 a year for 10,000 miles. If you switch to a smart tariff like Octopus Go or Intelligent Octopus (around 9p/kWh overnight), that drops to a super-low 2.6p/mile, costing only about £261 a year for 10,000 miles – a saving of £449 annually! Road tax is free until April 2025, after which it will be £195 per year. Insurance costs will vary but are generally competitive for this segment.

## Key stats

- **Fuel Type**: Electric
- **Horsepower**: 170-203 hp
- **Mpg**: N/A (Electric)
- **Reliability Score**: Good (backed by 7yr/80k mile warranty)
- **Safety Rating**: 5-star Euro NCAP (2022)

## Trim comparison

| SE | £26,995 | £11,000 | 10.25-inch infotainment system; 7-inch digital driver display; Rear parking sensors |
| SE Long Range | £29,495 | £12,500 | All SE features plus; Larger 64kWh battery; Increased 270-mile WLTP range |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £12,000 | 100% |
| 2027 | £10,500 | 87.5% |
| 2028 | £9,000 | 75% |
| 2029 | £7,800 | 65% |
| 2030 | £6,800 | 56.7% |

The MG4 has already taken a significant hit in depreciation since new, largely due to the broader EV market correction. This means you're buying it at a 'sweet spot' where much of the initial value loss has already occurred. While EVs will continue to depreciate, the rate should slow down, offering better value retention for second owners.

Total value lost since new: 43.33%.
