Aston Martin DB9 2010: MOT failure rate for its age
10.9% of 780 MOT tests of the Aston Martin DB9 first registered in 2010 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 94.2 (95% CI 74.2–114.2; 100 = normal for this model at that age): the 2010 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.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 10.9 | % | all ages tested | 2019–2024 | 780 |
| Index against this model at the same age (95% CI 74.2–114.2) | 94.2 | index | 100 = normal for this model at that age | 2019–2024 | 780 |
| Rank among this model's 8 build years | 3 | of 8 | 1 = fails least for its age | 2019–2024 | 780 |

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.
