Just to make you guys feel better....
In Brazil, it would cost you over USD120,000 for an base MY10 X3 30i, and over USD150,000 for a MY11 335 sedan, base.
I don't know the price for the MY11 X3
If you have a friend in the states that is ready to buy one for you... there is nothing stoping you from paying him for it and driving it up... you would need to pay taxes in the states and taxes to bring it up but there would't be any duties (NAFTA). There are a few companies that could help with the importation process as well.
