2017 BMW 440 MOT pass rate: 89.3% (4,374 tests)
Is the 2017 440 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.5% +3.8 vs same-age |
|
| 2024 | 88.7% +4.8 vs same-age |
|
| 2025 | 89.7% +7.3 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.

What mileage is too high for a 2017 440?
The median tested example shows 47,130 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.
