FAQs

Is a 2016 Mazda 6 reliable?

2016-registered examples passed 79.9% of their MOT tests (20,382 tests, 2023–2025), -1.4 points versus all UK cars registered in the same year. At roughly 10 years old with a median 74,178 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2016 6?

The median tested example shows 74,178 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.
