Jaguar S-Type 2001: MOT failure rate for its age
42.0% of 4,777 MOT tests of the Jaguar S-Type first registered in 2001 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 107.0 (95% CI 102.3–111.7; 100 = normal for this model at that age): the 2001 Jaguar S-Type fails more often than other build years of the same model at the same age.

How does the 2001 Jaguar S-Type fail at each age?
Cars built in 2001 were tested at ages 18 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.
| Age | Tests | Failed, % | 95% interval | Normal for this model at that age, % | Index (100 = normal) |
|---|---|---|---|---|---|
| 18 | 38 (rough estimate) | 44.7 | 30.1–60.3 | 42.5 | 105.2 |
| 19 | 1,531 | 43.2 | 40.8–45.7 | 39.8 | 108.6 |
| 20 | 1,321 | 42.8 | 40.2–45.5 | 39.4 | 108.9 |
| 21 | 1,076 | 42.8 | 39.8–45.7 | 39 | 109.6 |
| 22 | 849 | 37.6 | 34.4–40.9 | 38.4 | 97.8 |

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.
