Is the 2005 Altea getting worse?
Pass rate of 2005-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 60.6% -3.5 vs same-age |
|
| 2024 | 57.4% -6.9 vs same-age |
|
| 2025 | 59.8% -5.5 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.
