MOT Risk Index (2026). Daihatsu Copen MOT statistics 2024 (data release dvsa-2024-v2; full dataset motriskindex-families-2024-v5, DOI 10.5281/zenodo.22975051), updated 24 September 2026. motriskindex.co.uk/cars/daihatsu-copen/
How the MOT Risk Index and every figure on this page are calculated: methodology.
What is wrong on this page? One tap sends the category only, no text and nothing about you.
69.5% of first attempts passed in 2024 (1,280 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 1,280 primary tests: 30.55% failed first time and 74.1% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 72.2 is shown separately.
