My question involves a consumer law issue in the State of: Georgia.

Two weeks ago, I bought a car from a person who had advertised it as “sale by owner.”
He didn’t give me the title as he told me that he is a dealer, therefore I would get the title from the government tag office. He claimed he will do the paper work as required by law so that I get the title. Later, I went to tag office and I was told he has not submitted the paper work. When they checked the Vin number, they told me that the car is not registered here in Georgia. The officer in the Tag office asked me to bring an insurance bond, police report to show that the car was not stolen, and other forms that I have to fill.
When I called the guy, he denied that the car is not salvage (junk). I bought the history report which indicated that the car was wrecked in South Carolina last year. When I bought the car we both signed a bill of sale which disclaimed the warranties from him. I bought the “car as is” basis. I even noted that the driver’s window was not rolling down and the Ac was not working. I had inspected the car and found it fit, except that I didn’t check the windows and AC. I did repair out of my pocket. When I asked him about the title, he told me to give him the tax money so that he can apply for my title. In the bill of sale, it indicates ‘tax inclusive’. He is claiming that the discount he gave me was the tax money, so I have to pay extra money for him to apply for my title.
My question is, did the dealer commit Material misrepresentation on the sale as he did not disclose to me it was a salvage car? Do I have a case to sue, to get my money back as he takes his car back?

Thanks.
