It failed its MOT on 14 January 2026 (offside front suspension arm ball joint excessively worn; parking brake efficiency less than 50% of the required value) and passed later the same day.

Mileage at that test: 128,729 miles. The advert says 128,000 miles, fewer than the MOT record, so ask the dealer which is right.
