The 12 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 BMW 430s pass their MOT more often than older ones, by 4 percentage points on average, which is mostly down to age and wear.

Mileage Across Years
