Fiat 500L 2018: MOT failure rate for its age

22.5% of 2,437 MOT tests of the Fiat 500L first registered in 2018 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 102.1 (95% CI 93.6–110.6; 100 = normal for this model at that age): the 2018 build year is no different from other years of the same model at the same age. This is a rough estimate from a smaller sample.
