BMW wants to help U.S. Olympic athletes, but we're going to need your help to make that happen.  We know how that sounds, and no, we're not asking you to give any of your heard-earned money to the American Olympic teams.  Instead, all we're asking you to do is test-drive a new 2012 BMW 328i.  That's seriously all you have to do, and for every person that participates BMW will?
