Questions

What should I check when buying a used BMW M?

On a M, check service history; rod bearings; vANOS operation, on top of the checks for any used car: the body, tyres and engine, a test drive, and the paperwork for money owing, a write-off and the odometer.

About these numbers: the asking prices and odometer readings of M advertised for sale in the 12 months to November 2026, one listing per car. They are asking prices, not sale prices. The checklist for any used car.
