Hyundai i800 2012: MOT failure rate for its age
42.9% of 6,126 MOT tests of the Hyundai i800 first registered in 2012 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 101.1 (95% CI 97.2–104.9; 100 = normal for this model at that age): the 2012 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.
