2013 BMW 3 Series MOT pass rate: 79.2% (97,288 tests)
Is the 2013 3 Series getting worse?
Pass rate of 2013-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 80.8% +6.1 vs same-age |
|
| 2024 | 78.7% +5.5 vs same-age |
|
| 2025 | 78.1% +5.9 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 2013 BMW 3 Series reliable?
2013-registered examples passed 79.2% of their MOT tests (97,288 tests, 2023–2025), +5.9 points versus all UK cars registered in the same year. At roughly 13 years old with a median 101,221 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2013 3 Series?
The median tested example shows 101,221 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 2013 3 Series?
In this cohort petrols pass 82.9% of tests against 78.3% 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.
