You'll find you can actually take it to a small claims court, I did when I bought a corsa gsi a couple of years ago. Car was low mileage, been promised the cam belt had been done, ended up snapping about two weeks and 40 miles later. Phoned the guy and he said sold as seen, but wasnt stated on the receipt, ended up taking it to a small claims court who pursued the claim, ended up coming away with a reconditioned engine fitted, plus £200 in expenses/loss of earnings lol.
