The picture

720s V8 S-A: a strong MOT record by UK norms

Across 490 MOT tests, the 720s V8 S-A returns 93.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is windscreen or window excessively tinted. A broken or weak spring and number plate missing round out the top three. Average tested mileage sits at 11,210, 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.

Year-band analysis

Best year to buy. Worst to avoid.

Best band to buy

98.3%

Pre-2018 registration

the older band (pre-2018) climbs to 98.3% — a 3.0-point improvement. Failures here are mostly wear items: has a serious fluid leak, tread depth below requirements of 1.6mm — the structural issues that drag down older examples don't appear in the top-10 for this band.

95.3%

2018–2020 registration

On the 2018–2020 band, the data shows a 95.3% pass rate against a fleet average of 98.3% on the newer band. The main culprits logged at test: excessively tinted but not adversely affecting driver's view, fractured or broken, and damaged but not adversely affecting driver's view. Average mileage on test for this band is 12,516 miles — high-mileage wear items are a recurring theme.

Best band to buy: pre-2018 (98.3% first-time pass). Worst band to avoid: 2018-2020 (95.3% pass). That's a 3.0-point spread across 1,694 older tests and 811 newer ones — year of build makes a material difference on this model.
