How the ranking is built
Passenger cars of classes M1 and M1G only. A model is ranked when it has at least 100 main inspections in this age band. The measure is the first-attempt pass rate with its 95% confidence interval; no composite score and no hidden weights. Models with equal pass rates share a place. Methodology
