Talk about waste and abuse, taken from official site:

"What happens to the vehicle I trade in?
The CARS Act requires that the trade-in vehicle be crushed or shredded so that it will not be resold for use in the United States or elsewhere as an automobile. The entity crushing or shredding the vehicles in this manner will be allowed to sell some parts of the vehicle prior to crushing or shredding it, but these parts cannot include the engine or the drive train."
And IMHO this is nothing more than pumping money into the auto industry. A billion dollars at a time. I wonder who will *really* pay for this.
