2008 Mazda 6 MOT pass rate: 63.2% (9,954 tests)
Is the 2008 6 getting worse?
Pass rate of 2008-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 63.4% -2.0 vs same-age |
|
| 2024 | 63.0% -1.9 vs same-age |
|
| 2025 | 63.1% -2.1 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 2008 6?
