2014 BMW 420 MOT pass rate: 80.3% (22,950 tests)
Is the 2014 420 getting worse?
Pass rate of 2014-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 81.8% +4.4 vs same-age |
|
| 2024 | 80.1% +4.5 vs same-age |
|
| 2025 | 79.0% +4.6 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 BMW 420 reliable?

What mileage is too high for a 2014 420?
The median tested example shows 85,570 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.
