Used car rankings from MOT data
Most reliable used cars against cars the same age
We ranked 265 cars by how often they failed their MOT at 3 to 15 years old, each against all cars at the same ages. From 95,461,987 DVSA MOT tests in Great Britain, 2022 to 2025.
MOT data updated
First in this list: Porsche 911.
- Data: DVSA anonymised MOT test data, class 4 normal tests in Great Britain (England, Scotland and Wales), 2022 to 2025. Northern Ireland tests its cars separately and is not included. A fail is a test marked fail or passed after a repair at the test station.
- Measure: share of MOTs failed at each age from 3 to 15 years, pooled, against all cars at the same ages.
- Order: by the fail rate divided by the rate for all cars at the same ages, shown as the difference in per cent. Fail rates rise with age, so a ratio keeps a model seen only at older ages from looking better than it is.
- Comparison: all cars means every class 4 MOT test except vans, pickups, taxis, campers, van-based people carriers, motorhome and minibus bases and used imports, weighted to each row's own mix of ages.
- Thresholds: every age behind a row here has at least 5,000 tests. A model generation is ranked only with at least 3 ages of 1,000 tests or more, and a row needs at least 3 ages in this list. A list is published only with at least 10 ranked rows.
- Typical mileage: the median odometer reading at each age, averaged over the row's ages by number of tests.
- Vans, pickups, taxis, campers, van-based people carriers, motorhome and minibus bases, and models sold here mainly as used imports are left out of car lists.
- Years in brackets are the first-use years of a model generation.
The ranking
Mileage matters: a model driven less fails less often, and the typical mileage column shows how far each row's cars had gone. To compare cars at the same mileage, see cars over 120,000 miles, cars at 90,000 to 120,000 miles, cars at 60,000 to 90,000 miles.
