Toyota Celica 1999: MOT failure rate for its age
41.7% of 1,570 MOT tests of the Toyota Celica first registered in 1999 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 98.4 (95% CI 90.8–105.9; 100 = normal for this model at that age): the 1999 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 | 41.7 | % | all ages tested | 2019–2024 | 1570 |
| Index against this model at the same age (95% CI 90.8–105.9) | 98.4 | index | 100 = normal for this model at that age | 2019–2024 | 1570 |
| Rank among this model's 10 build years | 7 | of 10 | 1 = fails least for its age | 2019–2024 | 1570 |
| Tested in 2024 | 134 | tests | median 118,699 miles | 2024 | 134 |

How does the 1999 Toyota Celica fail at each age?
Cars built in 1999 were tested at ages 20 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) |
|---|---|---|---|---|---|
| 20 | 620 | 42.4 | 38.6–46.3 | 45.6 | 93.1 |
| 21 | 469 (rough estimate) | 42.9 | 38.5–47.4 | 40.7 | 105.2 |
| 22 | 481 (rough estimate) | 39.5 | 35.2–43.9 | 39.7 | 99.5 |

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.
