i dont recall the mpg that the gnx got but i know that the cash for clunkers had a cut off for mpg since the idea was to get non efficient vehicles off of the road. most gnx's are documented cars and i highly doubt some one gave even a beaten one (if it exists) up for 4500. a gnx in any moving condition has got to be worth much more. most of the cars in my area that i saw were worthless piles of trash that were so rusted away that they were not worth fixing. even though i am sure a few good cars were lost in this i have to say it was a great program to help boost the economy, not just the car companies. think about how many jobs were kept/created that were not there 6 months ago, really think about it..... dealers, sales people, tow companys, recyclers, lot guys washing cars, advertisers, truckers moving the cars, people doing paper work, banks, new loans that might help save the banks.......... allot of people were able to go back to work, allot of people that were collecting unemployment that we were paying for anyways!
