MINI Roadster 2014: MOT failure rate for its age

16.8% of 7,266 MOT tests of the MINI Roadster first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 95.5 (95% CI 90.1–100.9; 100 = normal for this model at that age): the 2014 build year is no different from other years of the same model at the same age.

How to cite this page

MOT Risk Index (2026). MINI Roadster 2014 MOT statistics (data release dvsa-2024-v2; full dataset motriskindex-families-2024-v5, DOI 10.5281/zenodo.22975051), updated 30 September 2026. motriskindex.co.uk/cars/mini-roadster/2014/

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.
