2005 BMW X3 MOT pass rate: 68.7% (7,644 tests)
Is the 2005 X3 getting worse?
Pass rate of 2005-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 68.3% +4.1 vs same-age |
|
| 2024 | 67.7% +3.5 vs same-age |
|
| 2025 | 70.7% +5.4 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 2005 BMW X3 reliable?
2005-registered examples passed 68.7% of their MOT tests (7,644 tests, 2023–2025), +4.2 points versus all UK cars registered in the same year. At roughly 21 years old with a median 138,854 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2005 X3?
The median tested example shows 138,854 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 2005 X3?
In this cohort petrols pass 72.4% of tests against 67.3% 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.
