About the 2008 MINI ONE

The 2008 MINI ONE is a small family car with a 1598cc petrol engine. 659 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It sits in the bottom 83% of 2008 cars for MOT pass rates.

With an average of 90,766 miles at 18 years old, MINI ONE owners tend to use this car less than the typical driver.

2008 MINI ONE Fuel Costs

The 1598cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,137 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

MINI ONE Reliability Trend

Newer MINI ONEs show better MOT pass rates than older ones, with an average improvement of 18 percentage points.

Buying a Used 2008 MINI ONE

At 18 years old, the MINI ONE is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2020 model has the highest pass rate at 94%.

Common Issues to Watch For

Based on the 2008 MINI ONE's fuel type, age, and engine size, these are the most likely problem areas to check.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Medium risk

With an average of 91k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

Higher Than Average Failure Rate

Watch out

With a 69% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
