Px 125: above-average pass rates, with caveats

Across 695 MOT tests, the Px 125 returns 84.8% first-time pass — above the UK fleet average. The single most-logged Major fail is direction indicator lamp missing. Mandatory tell-tale for direction indicators missing and a non-conforming number plate round out the top three. Average tested mileage sits at 13,228, 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 PX 125?

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.
