Consigning your car to a dealer or broker is simple. You either grant an exclusive or a non-exclusive right to sell your car to the dealer or broker of your choice. The cost of this option varies but is generally negotiable. A dealer is typically a licensed establishment with a permanent location or showroom that is open to the public. Brokers may or may not have a showroom, but tend to make connections between buyers and sellers based on their knowledge of the market and who wants to sell or buy at that moment. Both can make the selling process.
