Chrysler PT 2008: MOT failure rate for its age

42.3% of 511 MOT tests of the Chrysler PT first registered in 2008 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 87.1 (95% CI 75.5–98.7; 100 = normal for this model at that age): the 2008 Chrysler PT fails less 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.
