2018 BMW 435 MOT pass rate: 87.0% (3,933 tests)
Is the 2018 435 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.2% +1.2 vs same-age |
|
| 2024 | 87.3% +1.1 vs same-age |
|
| 2025 | 84.4% -0.4 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.
