First MOT test of each car per year in 2022–2024, from the DVSA’s anonymised test results; only ages with at least 500 tests are shown. The figure in brackets is the 95% confidence interval; green or red means clearly above or below the UK average. The second table shows how often an item was noted (defect or advisory) in each area, against the UK average for cars of the same ages. DVSA anonymised MOT tests (Open Government Licence)
