There are two prices, the MSRP and the invoice price. The dealer will do his best to let you buy with the MSRP as it is the desired price but you should start negotiation from the invoice price which is the price paid by the dealer.

Accessories and where to buy them

When you decide to buy a new car, your car agent will try to serve you the auto quote with full accessories and believe me if you try to get these accessories after the car hits the road it will be much cheaper so do not bother getting them from the dealer.
