2005 Mitsubishi Colt MOT pass rate: 62.1% (5,466 tests)
Is the 2005 Colt getting worse?
Pass rate of 2005-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 63.2% -1.0 vs same-age |
|
| 2024 | 61.6% -2.7 vs same-age |
|
| 2025 | 61.0% -4.3 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 2005 Colt?
