Is the 2020 C3 getting worse?

Pass rate of 2020-registered cars across recent test years:

Test year	Pass rate
2023	93.6% +2.7 vs same-age
2024	91.0% +1.0 vs same-age
2025	90.4% +1.5 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 C3 reliable?

2020-registered examples passed 91.7% of their MOT tests (14,384 tests, 2023–2025), +1.8 points versus all UK cars registered in the same year. At roughly 6 years old with a median 24,704 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2020 C3?

The median tested example shows 24,704 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.
