Focus St-Line X Edition Mhev: a strong MOT record by UK norms
Across 1,730 MOT tests, the Focus St-Line X Edition Mhev returns 91.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A seriously damaged tyre and a tyre with the cords showing round out the top three. Average tested mileage sits at 22,408, 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.
