Vauxhall Zafira 1999: MOT failure rate for its age

54.8% of 996 MOT tests of the Vauxhall Zafira first registered in 1999 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 106.2 (95% CI 97.3–115.1; 100 = normal for this model at that age): the 1999 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.
