FAQs

Is a 2008 Mazda 3 reliable?

2008-registered examples passed 60.4% of their MOT tests (18,261 tests, 2023–2025), -4.7 points versus all UK cars registered in the same year. At roughly 18 years old with a median 97,981 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2008 3?

The median tested example shows 97,981 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.
