You really need to shop around. I used USAA car buying program to find those dealers that might provide a good deal. There are lots of car buying programs out there through many different credit unions, etcetra. I have had the best luck with dealerships when I first search dealer inventories (either online or via salesman) and then contact a Sales Manager directly to see if he'll bite on the price. Bottom line is you have to be firm and make sure that you're getting not just a deal you can live with, but a great deal. If you are going for a 2009 Z, there is no reason in hell why any dealership couldn't sell them under invoice. Especially as we close in on December -- when the 2010 Z's come out and their 2009s instantly drop 5k in value.
