Lexus GS 2001: MOT failure rate for its age
33.5% of 741 MOT tests of the Lexus GS 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 106.3 (95% CI 93.1–119.6; 100 = normal for this model at that age): the 2001 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 |

| Index against this model at the same age (95% CI 93.1–119.6) | 106.3 | index | 100 = normal for this model at that age | 2019–2024 | 741 |
| Rank among this model's 18 build years | 15 | of 18 | 1 = fails least for its age | 2019–2024 | 741 |

How does the 2001 Lexus GS 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.

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.
