Vito,
Is this because you are a FFL/SOT? I believe they classify certain businesses that are High Risk and they sever ties. If this is the case you should try and get a FFL class action suit against them for discrimination.
I am a new car dealer and they give us capital loans, floor plan loans and even finance our retail contracts for customers. A car accident or a car used in a intended unintended manner to cause harm to a individual or individuals would seem to be a High Risk Industry to me. I guess we generate to much money for the greedy bastards. They need to stop listening to their lawyers and worry more about taking care of their customers. Send them a message a sue their pants off. This is blatant discrimination!!
