A genuine mistake having the mileage messed with? He's done this couple of times, on one of his ads he didn't even say there was anything wrong with the car, he made out it was mint etc, and it needed vsc sensor, rear door wouldn't open ot close, cd player didn't work and service history didn't ad up.
And it's funny he's always got an invoice for a cambelt change.
I think you need to read through it all again.
