Whether you buy a car under the program or not, one thing I can tell you from my recent car buying experience: The dealers of Big 3 are really humble. The bankruptcy (of GM & Chrysler), dealers closing down and the severity of recession have convinced them that their best days are over and they may not be in the business for long. You can sense a huge change in their attitude if you go there to buy a car.
Of course, you should do your homework and research prices etc., The dealer is not interested in you saving a lot of money; but the arrogance is definitely gone. Somewhat similar with realtors too.
