Of the years with at least 100 tests, the 2011 model has the highest pass rate at 93% from 2,579 tests. The 2006 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.

Reliability Trend

Newer Lexus IS250s pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Mileage Across Years
