500 Launch Edition Mhev: a strong MOT record by UK norms
Across 779 MOT tests, the 500 Launch Edition Mhev returns 87.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. A defective wiper blade and windscreen damage round out the top three. Average tested mileage sits at 15,801, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.
