The bank or finance company must sell the vehicle in a commercially reasonable manner. It is important to remember that when you signed the contract, you agreed to pay for the collection, repossession, legal, reconditioning, mechanics, ect fees.I would imagine that all of this is added to your existing balance that you owe. Ask the bank for a breakdown of your deficency balance.
According to Consumerlawpage.com, a resale of a repossessed car must be conducted in a "commercially reasonble manner". If you believe that your vehicle was resold for less than fair market value, the resale is not commercially reasonable. Contact an attorney, your car may have been sold to "a friend" for a substantially lower price than what the car is worth.
You do not need an attorney to sue in most states.Sue the bank for not selling the vehicle in a c.r.manner.This is a scam because all the banks do is hold a closed auction where the dealers who sold you the car get the same car back at a huge savings and start the game all over again.Oh yeah and then the bank sticks you with the difference.
