Is the 2010 A-Class getting worse?
Pass rate of 2010-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 71.8% +3.7 vs same-age |
|
| 2024 | 69.6% +2.5 vs same-age |
|
| 2025 | 68.8% +1.9 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.

What mileage is too high for a 2010 A-Class?
