I have just paid a £200 cash deposit on a used car at a trader's premises. We test drove it and the car appeared ok. At the time I had no internet access, however on return home I carried out a VOSA MOT history check. The check showed the vehicle as MOT'd on 10 August 2010 with 72,800 miles. Having gone through the test history, it would appear the car has actually lost around 28,000 miles since the test last year, and the previous test shows a higher mileage also. Am I entitled to my deposit back on this basis, being that the car is clearly not as advertised?
