Of the years with at least 100 tests, the 2007 model has the highest pass rate at 93% from 308 tests. The 2004 model has the lowest at 80%. The 13 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.

Newer Lexus SC430s pass their MOT more often than older ones, by 6 percentage points on average, which is mostly down to age and wear.

Mileage Across Years
