Puma St-Line Design Mhev: a strong MOT record by UK norms

Across 1,389 MOT tests, the Puma St-Line Design Mhev returns 93.5% 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 22,637, 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 Puma ST Line Design Mhev?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a Puma ST Line Design Mhev 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.
