Gt: a below-average pass rate worth digging into
Across 2,682 MOT tests, the Gt returns 63.4% first-time pass — well below the UK fleet average. The single most-logged Major fail is the strength or continuity of the load bearing. Worn suspension bushes and a lamp out round out the top three. Average tested mileage sits at 101,478, 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.

Counts cover Major and Dangerous defects logged at test. Advisory items excluded so this shows why a car was rejected, not just what the tester flagged in passing.

If every one of this GT's most-logged Major fails hit at the same MOT, that's the real-world UK garage range. Reality is usually one or two items, not all of them. Open the estimator →

Buying or keeping a GT?
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 GT 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.
