X3 M Competition Auto: a strong MOT record by UK norms

Across 1,161 MOT tests, the X3 M Competition Auto returns 92.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Tyre tread under the limit and windscreen damage round out the top three. Average tested mileage sits at 26,887, which is the lens to read those failure rankings through.
