Do you really think people are giving up on them, or are more people just moving on from them?I mean 500 is pretty cheap with new tires. I mean I don't know if you could fix the green one, and turn it for double money, but then you're also looking for parts yourself. So it becomes a catch 22. But personally I think 500 dollar 6th gens are a good thing. And think about it, you're helping the environment by being green and recycling.
