Five leaderboards from the ends of the MOT curve. The models that fail most and least, the cars you see everywhere, the ones the rust gets to, and the ones that go downhill fastest with age.
First-time MOT failure percentages from the 2025 results, retests excluded. Boards show the top eight models by each measure; the toggle switches the two failure boards between age seven and around 60,000 miles. The other three boards are the same either way. Bar lengths are relative to the leader within each board.
