Does the pass rate hold at higher mileage?
Pass rate by the mileage recorded at test, pooled across every published year. A car that stays strong past 90,000 miles is doing something right.

Both columns cover every published year for the model. Pass rates are test-weighted, so a model with more recent tests is not dragged down by its oldest ones. Repair figures are estimates from UK parts data; a garage quote is the only number that matters for a specific car. The same car can be tested in more than one year, so these are test outcomes, not a count of individual vehicles.
