The best thing I've ever seen were the BMW (and presumably other manufacturer) military/diplomatic sales deals out of Germany. 10-30% below US prices for some models, and 50+% below the local market prices in some countries. You email them, they send you a selector PDF, you reply with what you want and the price, and they take a deposit.

You have to be deployed military (although not necessarily to Europe), a contractor on specific orders, etc. to use the program, but it's pretty awesome if you can.
