Where this comes from: the DVSA's anonymised results for every MOT test done in Great Britain during 2023–2025, counting each car's main test of the year (not retests). A weak spot needs at least 30 cars flagged and must stay 1.5× the usual rate even at the cautious end of a 95% confidence range. Generation years are approximate: cars registered in a changeover year (*) can be either generation. How we score
