Fiat 124 2017: MOT failure rate for its age
10.7% of 4,298 MOT tests of the Fiat 124 first registered in 2017 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 98.8 (95% CI 89.8–107.9; 100 = normal for this model at that age): the 2017 build year is no different from other years of the same model at the same age.

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
