Is the 2019 420 getting worse?

Pass rate of 2019-registered cars across recent test years:

Test year	Pass rate
2023	88.2% -1.6 vs same-age
2024	87.5% -0.8 vs same-age
2025	86.1% -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 2019 BMW 420 reliable?

2019-registered examples passed 87.3% of their MOT tests (22,641 tests, 2023–2025), -1.1 points versus all UK cars registered in the same year. At roughly 7 years old with a median 39,105 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2019 420?

The median tested example shows 39,105 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.
