I use a program for work that allows me to configure and price vehicles. I can tell a customer or dealer exactly what a particular vehicle will cost to the penny. It calculates MSRP, Invoice, and Dealer pricing. I can do that for all the manufactures. I use it compare our pricing to Ford or Chrysler’s.
I don’t know what a “packed” invoice is, and I do not know about any management companies. I don’t know why a dealer would need a management company. Manufacturers train dealers how to manage their dealerships, and provide Regional sales and service managers to help them keep their business on track, manage their inventory, and stay profitable.
I do know in Chicago, there are brokers that procure vehicles from dealerships for customers, and many of the customers never go to a dealership. I’m sure there are additional fees they add on. However, those people still have the right to go into the dealership and deal directly. Still these vehicles are sold directly to the dealership by the manufacturer.
As far as why the Asian vehicles cost as much as those from U.S. manufacturers, vehicle prices are established based on what the market will bear. Haven you noticed that all the vehicles in a segment (compact, mid-size, etc.) are all priced about the same. That is by design. It wouldn’t matter if some manufacturer could produce the vehicle for a penny, they would still price them at the same level. The profit margin would just be higher. That’s why Japanese cars and trucks cost what they do.
GM now manufacturers cargo and cutaway vans with a CNG option direct from the factory. Although nothing has been released officially, the word is pick up truck will be next in a year or two.
