In Sept 2012 I bought a 2010 Audi Q5 from my local dealer. When I bought the car I specifically asked if it had any history of accidents, damage or repairs; I was told it had not.

Earlier this year I noticed the paint on the offside doors and the rear bumper was slightly faded. I also found a receipt amongst the pages in the owner’s manual for a £250 Insurance excess and an invoice from Audi Guildford. I contacted them and asked about the car's history and they told me it had been involved in a large accident in August a few weeks before I bought it.

I wrote to the Audi dealer I bought the car from and told them I rejected the car and wanted a full refund, as I specifically asked for a car with no previous damage history. However,they have refused to refund my money and instead offered to machine polish the car and respray the bumper. I find this totally unacceptable. What can I do?
