2018 Suzuki Swift MOT pass rate: 88.9% (29,894 tests)
Is the 2018 Swift getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 90.2% +2.1 vs same-age |
|
| 2024 | 89.1% +2.9 vs same-age |
|
| 2025 | 87.5% +2.8 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 Swift?
