2008 Signature Puretech S/S: a strong MOT record by UK norms
Across 922 MOT tests, the 2008 Signature Puretech S/S returns 87.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a number-plate lamp out. Rear registration plate lamp and tyre tread under the limit round out the top three. Average tested mileage sits at 27,039, 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.
