Petrol Alfa Romeo GT: MOT pass rate

66.9% of petrol Alfa Romeo GTs pass the MOT first time, measured across 717 DVSA tests on that fuel type alone. Average mileage at test was 87,851.

Petrol against the other Alfa Romeo GT versions

Why the fuel type changes the number

Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.

On the Alfa Romeo GT specifically, petrol is the strongest at 66.9%, and this petrol version sits 5.5 points above the 61.4% model average.

What it means if you are buying one

The petrol Alfa Romeo GT is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average petrol Alfa Romeo GT had covered 87,851 miles at test, against 113,868 for the diesel. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.

Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Alfa Romeo GT page separate age from fuel if you want to isolate one.

Most common MOT failures on a petrol Alfa Romeo GT

1. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 4.7% of tests (17.51x the national rate for this defect)
2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 5.6% of tests (13.64x the national rate for this defect)
3. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 8% of tests (8.45x the national rate for this defect)
4. Lambda coefficient outside the default limits or the range specified by the manufacturer, 2.5% of tests (4.85x the national rate for this defect)
5. Exhaust system leaking or insecure, 4% of tests (3.94x the national rate for this defect)
6. Windscreen washers not working or not providing sufficient fluid to clear the windscreen, 5.8% of tests (3.43x the national rate for this defect)
7. The aim of a headlamp is not within limits laid down in the requirements, 6.2% of tests (2.63x the national rate for this defect)
8. Engine MIL illuminated indicating a malfunction, 2.8% of tests (2.15x the national rate for this defect)

From 727 DVSA-tracked petrol Alfa Romeo GT tests, 2024, split out from the Alfa Romeo GT's other fuel types. DVSA testers marked 3.38% of these flagged defects as "dangerous", against 5.11% nationally.
