I disagree. I think that if Congress extends CARS (doubtful), it will be a one-time shot. The main reason is that there are still fiscal conservatives in Congress--the Blue Dog Democrats and the Republicans will team up to end the program. The Greenies won't support an extension because the current program, being a compromise, watered down the original premise of forcing people to trade up only to high-mileage cars.
CARS was fun while it lasted, but I predict it will shortly be as dead as one of the engines in my previous post.
