Used car rankings from MOT data

Used car rankings by MOT fail rate

107 rankings of used cars by how often they fail the MOT, from 130 million DVSA MOT tests in Great Britain (2022 to 2025). Every list compares model generations with cars the same age, shows the number of tests behind each figure and leaves out anything with too few tests.
