Expert verdict
Tyres: 2.9× the national share
Tyres make up 57.1% of everything recorded on the 2020 Bentley Bentayga Speed, against 19.8% nationally — 37.3 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 90.7% and this one manages 100.0% — 9.3 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 100% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.
