My brother bought a brand new Renault Megane from a Renault dealership in March 2008. Unbeknown to him this car was first registered on 1 August 2007 in Cyprus and was brought back to the UK, then sold at a Renault dealership to him as a brand new car with no registration plates on the car. He has been duped and the car company has told him as much. He said if he had known he was buying a car that was seven months old he wouldn't have bought it - he wanted a brand new car, but the twist to this is that three more cars came back from Cyprus (three Meganes), all registered in August 2007 in Cyprus and also sold at the same dealership. Somebody at the Renault dealership isn't telling the truth. What happens next?
