Suzuki Alto 2009: MOT failure rate for its age
35.7% of 35,135 MOT tests of the Suzuki Alto first registered in 2009 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 94.8 (95% CI 93.2–96.5; 100 = normal for this model at that age): the 2009 Suzuki Alto fails less often than other build years of the same model at the same age.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 35.7 | % | all ages tested | 2019–2024 | 35135 |
| Index against this model at the same age (95% CI 93.2–96.5) | 94.8 | index | 100 = normal for this model at that age | 2019–2024 | 35135 |
| Rank among this model's 13 build years | 1 | of 13 | 1 = fails least for its age | 2019–2024 | 35135 |

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.
