could anyone advise please On the 20th December I bought a 1999 Mitsubishi l200 pickup from a local dealer the asking price was £1990 with 7 months mot and 117000 miles Although there was no service history the truck looked in reasonable condition to me and the guy said he'd been using it himself and had had no problems. when I asked if the timing belts were changed he said his mechanic had looked over it and they were good. we agreed on a price of £1700 so I paid using a credit card. After I'd paid he gave me an invoice on which he'd highlighted a line saying discount given in lieu of any warranty given or implied. At the time I didn't really take much notice of that. last weekend (17h Jan) I decided to give it an oil and fuel filter change due to it running a little rough When I noticed the crankshaft pulley wobbling. I then realized that the bolt that holds it had broken off at some point and the pulley had been crudely welded to the crankshaft which was now breaking up. An engineer advised me that the crankshaft had been previously damaged and the weld was a botched attempt to repair it so would need replacing and not to drive the truck. I rang the dealer first thing Monday and explained but he was busy and said he would ring me back which he didn't. so, I rang again Tuesday This time he said there was nothing he could do as he didn't know about the welding plus it was an old vehicle so I should expect problems. I did mention the sales of goods act but he said as he'd knocked off £290 and the receipt said no warranty it didn't apply. the law was on his side I've not had any contact with him since as I thought that was that but, as I sit here having another sleepless night worrying about the mess I'm in I think there must be something I can do. can anyone help please I've only had it 4 weeks and done 370 miles
