You need to get in touch with the fraud division of your local police department. You need to file criminal fraud charges and then retain a lawyer to sue the dealers, who is ultimately libel for how his license is used. All the avenues you are pursuing are civil court stuff, cut out the small stuff and bring in some heavy artillery by filing under a criminal statute, you have obviously been defrauded, and the longer you wait to file charges the harder it will be. Just about any lawyer would be smacking his chops for a chance to sue them on contingency, go get you a well known meanie, you've got triple damages in royal flush spades.
