Of the years with at least 100 tests, the 2001 model has the highest pass rate at 76% from 192 tests. The 2004 model has the lowest at 70%. The 6 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Mileage Across Years
