Kia Optima 2014: MOT failure rate for its age
25.9% of 3,774 MOT tests of the Kia Optima first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 108.3 (95% CI 101.5–115.1; 100 = normal for this model at that age): the 2014 Kia Optima fails more 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.
