We bought a car on Auto Trader a week ago and paid in cash (£5550) but the car is registered under company name. We got 3 sets of keys, full up to 83k Audi dealer history. I was given the green slip of the v5, the original v5 was signed. After coming home I called the the guy (who posed as family man and as private seller) but his phone was dead. I contacted the police but I have been told there is no issue with the car. Later I found out that they have clocked the milage. It was on market with 96k but it is almost 136000. Now i am really worried that the car is stolen ?
