The picture
Vanquish: a strong MOT record by UK norms
Across 1,763 MOT tests, the Vanquish returns 91.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. A missing suspension dust cover and a missing suspension dust cover round out the top three. Average tested mileage sits at 21,551, 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 Vanquish?
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 Vanquish 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.
