Nissan 370Z 2009: MOT failure rate for its age

19.8% of 1,144 MOT tests of the Nissan 370Z first registered in 2009 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 127.7 (95% CI 111.1–144.4; 100 = normal for this model at that age): the 2009 Nissan 370Z fails more often than other build 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.
