A car dealership or vehicle local distribution is a business that sells new or used cars at the retail level, based on a dealership contract with an automaker or its sales subsidiary. Whether you're buying or selling a used car, you need to make sure to file all the paperwork and close the deal properly. While the laws governing the sale of motor vehicles vary from state to state, the general outline of the deal is similar. For the specific steps, make sure you check with the Department of Motor Vehicles in your state.
