You can see the invoice and incentives at Edmunds.com. When ready to purchase, get your financing in order, and go to the dealer. Don't speak to any salesman, but put your deal directly to the sales manager. If he says no, let him know there are 299 other dealers that want to move a unit. Leave your number, he might see he needs an extra sale to get a bonus and call you. I do it this way, and often have messages on my machine before getting home.
