The picture
R Ninet: a strong MOT record by UK norms
Across 3,196 MOT tests, the R Ninet returns 92.5% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-conforming number plate. Tyre tread under the limit and a missing rear reflector round out the top three. Average tested mileage sits at 7,133, 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 R Ninet?
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 R Ninet 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.
