Proceed Gt-Line Crdi Isg S-A: above-average pass rates, with caveats
Across 520 MOT tests, the Proceed Gt-Line Crdi Isg S-A returns 84.0% first-time pass — above the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Brake pads worn below 1.5 mm and wipers that don't clear the screen round out the top three. Average tested mileage sits at 45,065, 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.
