FAQs

Is a 2018 BMW X3 reliable?

2018-registered examples passed 90.0% of their MOT tests (24,050 tests, 2023–2025), +3.7 points versus all UK cars registered in the same year. At roughly 8 years old with a median 46,001 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 X3?

The median tested example shows 46,001 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.
