The picture
Unclassified: middle-of-the-pack on first-time pass
Across 3,565 MOT tests, the Unclassified returns 74.2% first-time pass — below the UK fleet average. The single most-logged Major fail is a number-plate lamp out. A split CV-joint boot and windscreen damage round out the top three. Average tested mileage sits at 84,024, 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.

Counts cover Major and Dangerous defects logged at test. Advisory items excluded so this shows why a car was rejected, not just what the tester flagged in passing.

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.
