Vauxhall Frontera 2004: MOT failure rate for its age

39.6% of 338 MOT tests of the Vauxhall Frontera first registered in 2004 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 89.7 (95% CI 74.5–104.9; 100 = normal for this model at that age): the 2004 build year is no different from other 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.
