Is the 2020 320 getting worse?

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

Test year	Pass rate
2023	88.1% -2.7 vs same-age
2024	89.0% -1.0 vs same-age
2025	88.7% -0.3 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 BMW 320 reliable?

2020-registered examples passed 88.6% of their MOT tests (12,163 tests, 2023–2025), -1.4 points versus all UK cars registered in the same year. At roughly 6 years old with a median 31,661 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2020 320?

The median tested example shows 31,661 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.
