Mazda Bongo 2001: MOT failure rate for its age

39.1% of 2,813 MOT tests of the Mazda Bongo first registered in 2001 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 85.6 (95% CI 80.5–90.7; 100 = normal for this model at that age): the 2001 Mazda Bongo fails less often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.

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.
