2007 Mercedes-Benz C MOT pass rate: 68.0% (38,374 tests)
Is the 2007 C getting worse?
Pass rate of 2007-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 67.4% +2.4 vs same-age |
|
| 2024 | 68.1% +3.2 vs same-age |
|
| 2025 | 68.7% +3.3 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 2007 C?
