Re: Mileage clocked ARGGGGHHH!!
Clocking a car, whether private or trade is an offence I'm sure.
As has been pointed out though, it may just be that the dash was changed. The mileage need not have been noted if the owner did it himself, but I would have expected the MOT station to pick up on it when the MOT'd it. It's all on a database these days and should have raised concerns.
