The picture
Unclassified: a strong MOT record by UK norms
Across 1,230 MOT tests, the Unclassified returns 87.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. Emissions levels exceed the manufacturer's specified limits and windscreen damage round out the top three. Average tested mileage sits at 10,188, 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 Unclassified?
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 Unclassified 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.
