Is the 2018 Grand C-Max getting worse?

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

Test year	Pass rate
2023	81.7% -6.4 vs same-age
2024	80.6% -5.6 vs same-age

FAQs

Is a 2018 Ford Grand C-Max reliable?

2018-registered examples passed 80.1% of their MOT tests (8,078 tests, 2023–2025), -6.2 points versus all UK cars registered in the same year. At roughly 8 years old with a median 43,748 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 Grand C-Max?

The median tested example shows 43,748 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.
