Some things to consider first.
1) Is the car dealership even in business anymore?
2) Are they the same company name?
3) Is the salesperson who sold you the vehicle still there?
4) Have you kept all your original documentation from the sale and do you have a specific time line of events?
5) Are you talking about a $2,000 car or a $20,000 car?
6) Are you certain that no where on any of the sales paperwork that it is disclosed to be salvage? It won’t matter what anyone said, only what the paperwork you signed says.
You need to get all this together and consider how much money you are out and then decide if you are willing to fight to get things set straight. Car dealers are scum, I’ve been there, I’ve heard countless stories and they will continue to swindle people left and right. Big car dealers will hide behind lawyers and little cars dealers will hide under rocks. They will not under any circumstances just come out and make it right.
If it were me I’d fight the battle if for no other reason than to put them on a watch list, to produce some negative publicity and to help impact their sales in a negative way. I would immediately get together all your documentation and approach the attorney general for your state. This should be a pretty easy case to get the state govt behind you as it appears the title system was abused. Prepare for battle.
The one thing that is going to give you trouble is that you are just now discovering the fraud. Some may claim caveat emptor and that you did not do your due diligence prior to purchase. It may turn out to be a hard lesson, but you’ll sure have learned from it.
Best of Luck.
