Alfa Romeo 147 2008: MOT failure rate for its age
45.8% of 3,924 MOT tests of the Alfa Romeo 147 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 94.1 (95% CI 89.8–98.5; 100 = normal for this model at that age): the 2008 Alfa Romeo 147 fails less often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 45.8 | % | all ages tested | 2019–2024 | 3924 |

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.
