2018 Vauxhall Adam MOT pass rate: 81.3% (16,082 tests)
Is the 2018 Adam getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 85.7% -2.3 vs same-age |
|
| 2024 | 82.0% -4.2 vs same-age |
|
| 2025 | 76.1% -8.6 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 2018 Adam?
