Cmx 500 A-X: a strong MOT record by UK norms

Across 1,083 MOT tests, the Cmx 500 A-X returns 92.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.0 mm. A non-functioning shock absorber and rate of flashing not between 60 round out the top three. Average tested mileage sits at 7,423, which is the lens to read those failure rankings through.
