Fund the U.S.A., Buy a Chevrolet

So my wife asks me the other day: For 2009 in lieu of paying federal income taxes could we just buy a car from one of the not-so-big-three U.S. manufacturers in an amount of at least our tax liability? That would bypass the government bureaucratic middle-man and give our bailout money directly to the recipient. By cutting out the handling fee more of our money would go right to the people who need it the most.
