650: middle-of-the-pack on first-time pass
Across 1,508 MOT tests, the 650 returns 79.5% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is worn suspension bushes. A missing suspension dust cover and worn suspension bushes round out the top three. Average tested mileage sits at 85,680, 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 650?
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 650 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.
