Of the years with at least 100 tests, the 2006 model has the highest pass rate at 81% from 510 tests. The 2002 model has the lowest at 67%. The 14 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 RX300s 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

The oldest model in our data (2000) averages 118,488 miles, while the newest (2006) averages 116,229 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.

Compared to the Lexus brand average of 87%, the RX300 is 12 points lower, placing it among the less reliable Lexus models.
