## Verdict

- **Best value year**: 2004
- **Ideal trim**: ZT 190 (V6)
- **Target mileage**: 70,000–90,000 miles
- **Max previous owners**: 4
- **Target price**: £3,500

## Why this model

The MG ZT is a fantastic choice if you're looking for something a bit different, with a real sense of occasion and a comfortable, well-appointed interior. It's essentially a sportier version of the Rover 75, offering a great blend of classic British charm and surprisingly engaging driving dynamics, especially in the more powerful V6 guise. It stands out from the crowd and offers a lot of car for the money, appealing to enthusiasts who appreciate its unique character.

## What you should pay

Prices for the MG ZT are generally low, reflecting its age and niche appeal. However, well-maintained examples, particularly the desirable ZT 190 V6 or ZT-T estate, are starting to see their values stabilise and even slightly increase as they become modern classics. You're buying into a passionate owner community, which helps with parts and advice. Don't expect it to be a massive investment, but a good one won't lose much more money.

## Which trim to buy

The ZT 190 with its 2.5-litre V6 engine is the sweet spot for enthusiasts. It offers a smooth, powerful engine with a lovely exhaust note, making it genuinely quick for its era. It also tends to be more robust than the K-Series four-cylinder models, particularly regarding the infamous head gasket issues. You get a great blend of performance, comfort, and that distinctive ZT character, making it the most desirable and rewarding trim to own.

## What to check before you buy

- K-Series engine head gasket failure (check if upgraded)
- Cooling system leaks (radiator, hoses, thermostat)
- Electrical gremlins (windows, central locking, dashboard lights)
- Front suspension bushes wear
- Air conditioning system failure

## Running costs

Running an MG ZT can be a mixed bag. Fuel costs for the V6 (ZT 190) will be higher, expect around 25-30 pence per mile at current petrol prices. Road tax (VED) for a 2004 2.5L V6 will be in the higher band, around £395 per year. Insurance can be reasonable for an older car, but performance trims might be a bit more. The biggest factor will be maintenance; while parts are generally available, finding specialists and addressing common issues (like the cooling system or potential K-Series head gasket) can add to costs. Budget for preventative maintenance.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 160-190 bhp (depending on engine)
- **Mpg**: 25-30 mpg
- **Reliability Score**: Fair (known issues, but robust if maintained)
- **Safety Rating**: Not rated by modern Euro NCAP standards

## Trim comparison

| ZT 120 | £17,000 | £1,800 | 1.8L K-Series engine; Manual gearbox; Cloth upholstery |
| ZT 160 | £20,000 | £2,800 | 2.5L KV6 engine; Manual or automatic gearbox; Half-leather sports seats |
| ZT 190 | £22,500 | £3,500 | 2.5L KV6 engine (190bhp); Manual or automatic gearbox; Full leather sports seats (optional) |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £3,500 | 100% |
| 2027 | £3,400 | 97% |
| 2028 | £3,300 | 94% |
| 2029 | £3,200 | 91% |
| 2030 | £3,100 | 89% |

The MG ZT has long passed its main depreciation curve. Its value is now largely dependent on condition, mileage, and service history, particularly for desirable trims like the ZT 190. A well-maintained example might even see a slight increase in value over time as a modern classic, rather than a significant loss. You're buying it at or near its lowest point.

Total value lost since new: 10%.

## Alternatives to consider

- BMW 3 Series (E46)
- Audi A4 (B6)
- Ford Mondeo ST220
