i recently bought an astra 1.7ctdi from a garage in preston.we agreed a price etc and he said there would be no warranty which i accepted. upon getting the vehicle home i realised the speakers werent working and upon investigation found that there was no wiring or speakers except to the drivers side.also the radio station was convieniently programmed to a station that didnt require an ariel .. as there wasnt one. a week later i took the car out and it over heated and blown the head gasket. it has also developed a knocking noise. going through the paperwork i got with the car i.e service history it appears its not a new problem although it wasnt mentioned at time of sale. we agreed the price then he went to get the paperwork from a garage down the road. im at a loss what to do .. at the moment i have a 4000 pound car and no money to mend it .... could anyone put me out my misery and tell me if i have any rights . thankyou.
