13.3% of 315 MOT tests of the Mercedes-Benz G first registered in 2016 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 166.5 (95% CI 116.2–216.9; 100 = normal for this model at that age): the 2016 Mercedes-Benz G fails more 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.
