Mercedes-Benz CL 2002: MOT failure rate for its age
26.7% of 1,440 MOT tests of the Mercedes-Benz CL first registered in 2002 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 104.9 (95% CI 94.4–115.4; 100 = normal for this model at that age): the 2002 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 | 26.7 | % | all ages tested | 2019–2024 | 1440 |
| Index against this model at the same age (95% CI 94.4–115.4) | 104.9 | index | 100 = normal for this model at that age | 2019–2024 | 1440 |
| Rank among this model's 9 build years | 4 | of 9 | 1 = fails least for its age | 2019–2024 | 1440 |

How does the 2002 Mercedes-Benz CL fail at each age?
Cars built in 2002 were tested at ages 17 to 22 between 2019 and 2024. Each row compares their first-time failure share with what this model normally shows at that age, after allowing for the overall failure level of each test year.

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.
