And this is why I don't sell cars
Its a tough business...There is so little on the table sometimes that it just doesn't make sense for the dealer to let it go a certain amount. The last thing they want to see is you walk out the door without your new car, but it has to make sense from a business standpoint as well!
I'd say your best deal was at the first dealership...hopefully they haven't sold it already. I used to work in real estate and I can't tell you how many times I gave people a great deal on a new home...they decided to think about it (shop around for a bigger better deal) and by the time they came back it was sold. Then they'd get upset with me cuz it wasn't available anymore!
