I've just been doing some digging and ringing places that the car had been at. August 2022: 12986 (Purchased) November 2024: 14431 (Service) ** Bought second car, expect mileage to significantly reduce, maybe expect 3k per year max as I WFH, and we've had two kids since having the car June 2024: 21165 (Service) December 2024: 35967 (MOT) October 2025: 30858 (Service) November 2025: 30977 (I noted it for car insurance) December 2025: 31550 (MOT) Looking at the history, I think it points at the December 2024 number being input wrong by the garage. At least, more than some glitch with the car... How frustrating as I guess this could impact future sale. EDIT: 35967 doesn't make sense though, 30967 would still be higher than almost a year later. Huh. Maybe it was 25967...
