How we build this guide
We combine official UK data with what independent garages see most often on this model.
- How many are still on the road: DfT vehicle licensing statistics, by year first used. The survival comparison is against cars of the same age.
- MOT pass rates, failures and mileage: DVSA anonymised MOT results — every normal car MOT in Great Britain for the year, compared with all cars of the same age.
- Road tax: GOV.UK rates from April 2026. ULEZ: TfL and Clean Air Zone emission standards.
- Faults and repair costs: known problems by engine code, priced at typical UK independent-garage rates including parts and labour.
- Insurance groups, mpg, servicing and tyres: typical ranges, not quotes. Your car's exact figures depend on the version and where you live.
This is a buying guide, not a mechanical inspection. A specific car's MOT history tells you far more than any model average — run a free check on it before you go and see it.
