# Mercury Unclassified MOT reliability: pass rate and common failures | RegFlags

The Mercury Unclassified passed its MOT first time 91% of the time, but from only 11 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 91%
- MOT tests analysed: 11 (DVSA anonymised MOT data, 2025)
- Most common failure area: Seat belts & other equipment

These figures come from only 11 MOT tests. With so few cars, a single pass or fail changes the percentages a lot, so treat them as a rough guide rather than a true average.
