Is the 2017 One getting worse?

+2.7 vs same-age
202489.4%
+5.5 vs same-age

FAQs

Is a 2017 MINI One reliable?

2017-registered examples passed 88.8% of their MOT tests (15,904 tests, 2023–2025), +4.8 points versus all UK cars registered in the same year. At roughly 9 years old with a median 41,168 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 One?

The median tested example shows 41,168 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
