Another way of looking at it is that in a competitive market which both car manufacturing and sales definitely are , savings to the consumer can only be achieved through improved efficiencies . Manufacturers and dealers already do a pretty good job producing and ordering cars people want to buy . There are probably about the right number of new car retailers , with some exceptions see Cadillac and Project Pinnacle . Maybe you could eliminate dealer advertising , but I suspect the spending would just move around to manufacturer standardized ads . What ' s left is the efficiency of the sales force . Perhaps you could save money moving to noncommissioned hourly staff like CarMax , but without proper incentives you risk losing market share to competitors through lazy salespeople .
