The picture
Db9: a strong MOT record by UK norms
Across 4,692 MOT tests, the Db9 returns 89.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a lamp out. The engine warning light staying lit and windscreen damage round out the top three. Average tested mileage sits at 39,379, 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.
