I think that maybe the fuel economy reasoning for doing this program that is being put forth is an afterthought, a "side effect" if you will.
I think the real reason may be just to stimulate the economy (get us consumers buying) and put some money in the pockets of the moribund American auto industry.
I looked at that car list and wow, those are some nice clunkers!!!
What am I driving then a "sub-clunker"?
I guess it comes down to which side of the car equation one is most comfortable on.
If I buy a new car with a down payment and a loan I can be pretty sure that my only operating expenses will be insurance, loan payment, gas and some service although most manufacturers have pretty nice service programs.
If I buy a used car, pay cash and own it outright I will have maintenance and repair
from the onset, gas, and insurance (which should be less for a used vehicle).
I have owned one car only (my z) for 13 years.
That should tell you where I sit.
PS. I don't see this as a political thread because I don't see anyone blatantly preaching and it is about automobiles after all... But that's just my perception.
