2011 Citroen C1 MOT pass rate: 71.0% (40,493 tests)
Is the 2011 C1 getting worse?
Pass rate of 2011-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 73.3% +3.2 vs same-age |
|
| 2024 | 70.5% +1.6 vs same-age |
|
| 2025 | 68.9% +0.5 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 2011 C1?
