The car salesman leads you to believe invoice is true dealer cost. True dealer cost could be a $1000 or more. I learned this when I worked for a GM dealer when I was in my 20's. The salesman gets his commission from selling a vehicle. Any list of accessories he sells he gets a nice percentage of that money. His salaried manager gets about half the commission of each salesman. The dealership also gets money from the manufacture for selling the car. At the end of the year the dealership gets a nice kickback from the manufacture for how many trucks or cars they sold that year. In my day it was the Impala. The dealer also receives, manfacture money for the total amount of vehicles they sold that year.

The GM method may have changed over the years. Toyota may work there sales completely different. I do know that Toyota has the best management of all the vehicle manufactures. There quality of management and ability for good training may be why Toyota has moved to be the top auto company.

I learned a lot with the GM sales job. I was told it would cost 'twice as much' if you assembled a new car from the parts department. There must be a nice profit in car parts, thus the many auto stores around town.

My manager quit working at this GM dealer. He went out in the edge of Dallas and started his own new Motor Home lot. His first year he made over $400,000. I could have worked as a salesman there. I worried about showing the insides of a motor home in the hot July Dallas heat. I was gifted more in electronics.
