Which Proton fails its MOT most, and which least?
The Proton 13 has the highest failure rate at 36.1%, and the Proton Sl the lowest at 28.9%. A higher rate reflects how old and how hard a model tends to be used as much as how it was built, so the oldest models in the range usually sit near the top.
