418: above-average pass rates, with caveats
Across 1,186 MOT tests, the 418 returns 82.4% first-time pass — above the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Windscreen damage and a tyre with the cords showing round out the top three. Average tested mileage sits at 82,150, 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 418?
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 418 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.
