Aston Martin DB11 2016: MOT failure rate for its age
5.9% of 523 MOT tests of the Aston Martin DB11 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 110.7 (95% CI 71.7–149.6; 100 = normal for this model at that age): the 2016 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 | 5.9 | % | all ages tested | 2019–2024 | 523 |
| Index against this model at the same age (95% CI 71.7–149.6) | 110.7 | index | 100 = normal for this model at that age | 2019–2024 | 523 |
| Rank among this model's 5 build years | 5 | of 5 | 1 = fails least for its age | 2019–2024 | 523 |

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.
