Is the 2014 Cooper getting worse?

Pass rate of 2014-registered cars across recent test years:

Test year	Pass rate
2023	86.0% +8.6 vs same-age
2024	85.2% +9.5 vs same-age
2025	84.7% +10.3 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2014 MINI Cooper reliable?

2014-registered examples passed 85.3% of their MOT tests (56,247 tests, 2023–2025), +9.5 points versus all UK cars registered in the same year. At roughly 12 years old with a median 62,224 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2014 Cooper?

The median tested example shows 62,224 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.

Should I buy the petrol or diesel 2014 Cooper?

In this cohort petrols pass 86.5% of tests against 82.7% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
