2020 Citroen C1 MOT pass rate: 91.7% (9,757 tests)
Is the 2020 C1 getting worse?
Pass rate of 2020-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 94.4% +3.5 vs same-age |
|
| 2024 | 90.9% +0.9 vs same-age |
|
| 2025 | 89.8% +0.9 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.

FAQs
Is a 2020 Citroen C1 reliable?

What mileage is too high for a 2020 C1?
The median tested example shows 17,532 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
