500 Star S-A: a strong MOT record by UK norms
Across 499 MOT tests, the 500 Star S-A returns 88.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. Wipers that don't clear the screen and a seriously damaged tyre round out the top three. Average tested mileage sits at 13,818, 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.

Buying or keeping a 500 Star S A?

If you own a 500 Star S A and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
