FAQs

Is a 2017 BMW 120 reliable?

2017-registered examples passed 87.2% of their MOT tests (6,901 tests, 2023–2025), +3.2 points versus all UK cars registered in the same year. At roughly 9 years old with a median 56,606 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 120?

The median tested example shows 56,606 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.
