One Clubman: middle-of-the-pack on first-time pass
Across 786 MOT tests, the One Clubman returns 77.6% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. A number-plate lamp out and a lamp out round out the top three. Average tested mileage sits at 75,549, 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 One Clubman?
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 One Clubman 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.
