2015 Vauxhall Adam MOT pass rate: 72.7% (32,000 tests)
Is the 2015 Adam getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 76.8% -3.7 vs same-age |
|
| 2024 | 73.1% -5.4 vs same-age |
|
| 2025 | 68.1% -8.9 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 2015 Adam?
