Best and Worst Years
Of the years with at least 100 tests, the 2020 model has the highest pass rate at 90% from 13,840 tests. The 2006 model has the lowest at 74%. With a 16 point gap, the year you choose makes a real difference. Newer cars usually pass more often simply because they are younger.
Reliability Trend
Newer SEAT Leons pass their MOT more often than older ones, by 9 percentage points on average, which is mostly down to age and wear.
Mileage Across Years
The oldest model in our data (2000) averages 108,063 miles, while the newest (2021) averages 29,531 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
Compared to the SEAT brand average of 85%, the Leon is 4 points lower, placing it among the less reliable SEAT models.
