2018 Toyota Aygo MOT pass rate: 90.3% (64,756 tests)
Is the 2018 Aygo getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 91.4% +3.3 vs same-age |
|
| 2024 | 89.6% +3.4 vs same-age |
|
| 2025 | 89.8% +5.0 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 Aygo?
