The picture
F430: a strong MOT record by UK norms
Across 1,219 MOT tests, the F430 returns 92.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a torn steering gaiter. A torn suspension dust cover and a weak handbrake round out the top three. Average tested mileage sits at 23,492, 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 F430?
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 F430 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.
