FAQs

Is a 2022 Mercedes-Benz A reliable?

2022-registered examples passed 92.8% of their MOT tests (4,161 tests, 2023–2025), +1.5 points versus all UK cars registered in the same year. At roughly 4 years old with a median 21,854 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2022 A?

The median tested example shows 21,854 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.
