2010 Lexus IS250 MOT pass rate: 83.6% (3,544 tests)
Is the 2010 IS250 getting worse?
Pass rate of 2010-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 84.0% +15.9 vs same-age |
|
| 2024 | 83.7% +16.7 vs same-age |
|
| 2025 | 83.2% +16.3 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.
