BMW 330 years to avoid: the later ones
Based on 20,836 real MOT tests from DVSA records. Each year is compared against every other car first registered the same year — otherwise the numbers would only tell you that older cars fail more, which you knew.
The short answer
Avoid 2019 to 2020. The worst is the 2020, which fails its MOT 64% more often than other cars of the same age. The 2016 is the strongest, failing 27% less often than average.

Averages tell you what to expect. Its registration tells you what actually happened — every MOT, every advisory, and whether the mileage adds up.

How this is worked out
Every MOT test recorded by DVSA in 2023 on a BMW 330, grouped by the year the car was first registered. Retests are excluded, so a car that failed and was fixed still counts as a failure. Each year's rate is then divided by the rate for all cars first registered that year — so 120 means 20% more failures than its contemporaries, not 20% more than a brand new car.
