Best Year to Buy?
Of the years with at least 100 tests, the 2021 model has the highest MOT pass rate at 95%, while the 2015 model has the lowest at 89%. The 2022 scores 96%, but cars from 2022 weren't due their first routine MOT until 2025, so its figure isn't compared here. Newer cars usually pass more often simply because they are younger, so compare years of a similar age.
