The picture
Xt600: a strong MOT record by UK norms
Across 690 MOT tests, the Xt600 returns 87.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a binding brake. Lamp not securely attached and a worn shock-absorber bush round out the top three. Average tested mileage sits at 24,884, 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 Xt600?
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 Xt600 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.
