The Congress led arbitration hearings for almost 2,800 GM and Chrysler dealerships that were to be closed last year will soon come to an end. Since the hearings began, many of the cases have been resolved outside of arbitration. Some dealerships dropped out of the process on their own, others decided to start selling other brands, and some could still face months of litigation in state courts. While GM agreed that it would restore more than 660 dealerships and Chrysler about 80, the actual numbers will not be known until the arbitration is complete.
