FAQs

Is a 2008 BMW 520 reliable?

2008-registered examples passed 75.1% of their MOT tests (8,193 tests, 2023–2025), +9.9 points versus all UK cars registered in the same year. At roughly 18 years old with a median 150,792 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2008 520?

The median tested example shows 150,792 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.
