What can be done about a dealer not telling me a car I bought was salvaged?

Does the title have salvage on it, if it was a salvage , its got a salvage title , and they wont resale but about half, on this , id take the son a of gun to court over this , and take all paper work with me, and stick it to hi m, and tell him , i said to , lol it wont make a diff, but tell him any way, he is a low down no good bum to do a lady like this, i sell cars some times at my sons lot and we never ever do this, so lay it to him , the warranty , dont make it right, its the title

Currently I found out the dealer did put the title as repaired and not salvaged. The dealer is the one who fixed the vehicle and my mechanic says it will cost me $5,000 to repair the damage that the dealer so poorly repaired. This vehicle is not safe for anyone to drive. The warranty did say as is on it but I still feel as if I got stiffed by a dealer who cheated me and broke the law. How can I prove my word against his word? How can I win this?

I think if you just keep after him and not let up that you can get him to fix whats wrong with the trade, i just dont like this kind of busniess, and dont let up on him till he gives your money back
