Hi All, I think i have no hope but wanted to ask. I have purchased a used car from a dealer ( so called, advertised as dealer and held log book as dealer but sold from home ) on Autotrader. I had a friend of mine go and check the car for me, he took it for a test drive etc and all seemed well. We went and collected it, filled in all the paperwork etc and drove away. Twenty minutes later the temp shot right up and we had to pull over, engine was boiling, AA attended and had to tow us home. Mechanic says a new head gasket is needed and that the car has a bottom end knocking ( ive no idea what this means ) and the engine, even if the head is repaired, has a few months in it at best. I contacted the sellar, who initially told me to get lost, i told him id taken legal advice etc and he agreed to get the head fixed, but only at a garage of his choice ( a mate probably ) and we would have to transport the car the 50 miles to the garage. I want a full refund, he has withheld the advisory notice from the MOT, i have taken the car to another garage who said it would never have gone through an mot, yet he has a certificate from 11th June 2010. Is there anyway i can back him into a corner to get a refund , he has written sold as seen all over the reciept and currently has other cars on autotrader listed as a dealer. Thanks J
