I will not quote my husband's reply.
Free consultant doesn't cost anything but time; can get a few free consultations.
Can write his own letter asking for his money back or else will hire a lawyer, and dealer will have to pay for lawyer, too.
Anyway, good luck.
According to my lawyer husband, who is on a board of directors and counsel to dealership. He said he would sue - hire a lawyer. Lawyer, after going over everything, will tell you if you have a case.
