Dacia Sandero 2018: MOT failure rate for its age
21.8% of 51,008 MOT tests of the Dacia Sandero first registered in 2018 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 97.6 (95% CI 95.8–99.5; 100 = normal for this model at that age): close to other build years of the same model at the same age (within 5 points of normal).
| Measure | Value | Unit | Compared with | Years | Tests |

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.
