FAQs

Is a 2006 BMW 120 reliable?

2006-registered examples passed 71.3% of their MOT tests (6,420 tests, 2023–2025), +6.9 points versus all UK cars registered in the same year. At roughly 20 years old with a median 136,854 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2006 120?

The median tested example shows 136,854 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.

Should I buy the petrol or diesel 2006 120?

In this cohort petrols pass 77.9% of tests against 70.4% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
