## Why this model

The MG TF is a fantastic little British roadster that offers pure, unadulterated open-top fun without breaking the bank. It's got a classic sports car feel, with direct steering and a lively engine, making even short drives a blast. While it does have a few well-known quirks, a well-maintained example can be a really rewarding car to own, especially if you're looking for something with character and a strong enthusiast community.

## What you should pay

Prices for the MG TF are relatively low, making it an accessible entry into classic sports car ownership. The key is condition over mileage or year. A well-looked-after car with a documented history of head gasket replacement and cooling system maintenance will command a premium, but it's worth paying for peace of mind. Avoid the cheapest examples unless you're prepared for significant repair bills.

## Which trim to buy

The TF 135 offers the best balance of performance and value. It uses the more powerful 1.8-litre K-Series engine (135bhp) which gives it a good turn of pace, without the higher insurance or potential mechanical stress of the more powerful 160bhp version. It's also more common than the 160, meaning more choice on the used market. Look for one with the optional hardtop for year-round usability.

## What to check before you buy

- Head gasket failure (HGF) - check for milky oil, overheating, or coolant loss.
- Cooling system leaks (radiator, hoses, expansion tank).
- Rear subframe corrosion.
- Electrical gremlins (windows, central locking).
- Water ingress into the cabin (check carpets and boot).

## Running costs

Running costs for an MG TF are generally reasonable for a sports car of its age. Fuel economy is around 35-40 mpg. Road tax (VED) for a 2005 1.8L model is currently £325 per year. Insurance can be surprisingly affordable, especially if you opt for classic car insurance, but parts for some specific items might be harder to source or more expensive than a modern hatchback. Budget for regular maintenance and potential repairs, particularly around the cooling system.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 135 bhp
- **Mpg**: 35-40 mpg
- **Reliability Score**: Average to below average. Known for cooling system and head gasket issues, but otherwise simple mechanics.
- **Safety Rating**: Not rated by Euro NCAP (pre-2000s standards, expect basic safety features).

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| TF 115 | £0 | £2,500 | 1.6L K-Series engine (115bhp); Cloth seats; 15-inch alloy wheels |
| TF 135 | £0 | £3,500 | 1.8L K-Series engine (135bhp); Half-leather seats; 16-inch alloy wheels |
| TF 160 | £0 | £4,500 | 1.8L K-Series VVC engine (160bhp); Full leather seats; 16-inch 'Abingdon' alloy wheels |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £3,500 | 0% |
| 2027 | £3,400 | 2.86% |
| 2028 | £3,300 | 5.71% |
| 2029 | £3,200 | 8.57% |
| 2030 | £3,100 | 11.43% |

The MG TF has largely passed its main depreciation curve. Its value is now more dependent on its condition, service history, and originality rather than age alone. Well-maintained, low-mileage examples, especially the rarer 160 models, might even see slight appreciation over time as they become more sought-after modern classics. You're buying into a stable, enthusiast-driven market.

Total value lost since new: 11.43%.

- Mazda MX-5 (NB/NC)
