94.3% of MG 4s passed the 2024 MOT (a rough estimate from 966 first tests): 92.8% at the first attempt and 1.6% after a fix at the test centre (PRS), each rounded separately. About 1 in 10 failed the first attempt. For its age, it is statistically indistinguishable from normal: MOT Risk Index 91.2 (95% CI 72.6–113.9; 100 = normal).

What is wrong on this page? One tap sends the category only, no text and nothing about you.
92.8% of first attempts passed in 2024 (966 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 966 primary tests: 7.25% failed first time and 94.3% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 91.2 is shown separately.
