L C H Cars in Todmorden

I bought a Mercedes Vito van, the advert said it was in excellent conditions and even mentioned things that the van didn't have like electric wing mirrors. I bought the van after traveling 6 hours on the train to see it and 52 miles into my journey home, the van went into limp mode. I rang him he said to switch the engine on and off and it may reset, I tried it didn't, so I rang him back he said as long as the van is driving and there are no warning stop lights on I should get home in it. I did eventually get home 6.5 hours later at 45 -50 miles an hour, he had reassured me that I could take it to a VAT registered garage for repair and it wouldn't be a problem. I have done this to find out at a cost of £145.00 for the diagnostics that the turbo is seized and the 4 glow plugs are also knackered, I have said to LCH it's going to cost just short of £1200.00 to repair as a gesture of goodwill on my part as I would prefer a brand new turbo and not a reconditioned one that I will go halves on the repair bill, I couldn't be much more reasonable I think, and still they are messing me around, they even asked me to drive a non road worthy van back to Todmorden from Wales, I just want people to be very sure when buying a motor vehicle from here that they have a very good mechanic with them as the three month warranty they give with their vehicles don't seem to be very good.
