Thanks, you may well be right and I am expecting to be fobbed off. However I’d like to think I’d be in a slightly stronger position on this than the normal caveat emptor position that would apply if I was just complaining about the condition of the car or something. I’m pretty sure it’s illegal to sell a clocked car and the CCPC seem to take it pretty seriously:

Perhaps the threat of a complaint to them would be enough to get the seller to play ball and take the car back?
