2012 BMW 120 MOT pass rate: 72.3% (7,315 tests)
Is the 2012 120 getting worse?
Pass rate of 2012-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 72.2% -0.2 vs same-age |
|
| 2024 | 73.5% +2.5 vs same-age |
|
| 2025 | 71.4% +1.1 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 2012 BMW 120 reliable?
2012-registered examples passed 72.3% of their MOT tests (7,315 tests, 2023–2025), +1.1 points versus all UK cars registered in the same year. At roughly 14 years old with a median 98,552 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2012 120?
The median tested example shows 98,552 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 2012 120?
In this cohort petrols pass 78.0% of tests against 71.8% 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.
