Arnage: a strong MOT record by UK norms
Across 1,614 MOT tests, the Arnage returns 86.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. A torn suspension dust cover and a missing suspension dust cover round out the top three. Average tested mileage sits at 59,433, 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 an Arnage?
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 an Arnage 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.
