Spitfire: middle-of-the-pack on first-time pass
Across 649 MOT tests, the Spitfire returns 80.0% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is brakes imbalance across an axle such. Emissions levels exceed default limits and a weak handbrake round out the top three. Average tested mileage sits at 48,249, 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.
Top ten reasons for rejection.
- 01
Brakes imbalance across an axle such that the braking effort from any wheel is less than 70% of the maximum effort recorded from the other wheel on the same axle.

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.

Buying or keeping a Spitfire?
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 Spitfire 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.
