Best and Worst Years
Of the years with at least 100 tests, the 1992 model has the highest pass rate at 78% from 224 tests. The 1990 model has the lowest at 77%. With just a 1 point gap, pass rates are similar across these years. Newer cars usually pass more often simply because they are younger.
Mileage Across Years
