Is the 2018 B-Max getting worse?

Pass rate of 2018-registered cars across recent test years:

Test year	Pass rate
2023	84.5% -3.5 vs same-age
2024	78.0% -8.2 vs same-age
2025	73.2% -11.6 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 2018 Ford B-Max reliable?

2018-registered examples passed 78.6% of their MOT tests (2,043 tests, 2023–2025), -7.7 points versus all UK cars registered in the same year. At roughly 8 years old with a median 31,974 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 B-Max?

The median tested example shows 31,974 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.
