I don't get the green machine thing. It's all about the collecting and not about the truck. I mean, it's great to buy a limited/lower production version from the collecting point of view, but from the truck point of view, whats so cool about one with goofy green wheels/hubcaps that detract from the appearance? With Hot Wheels ones with better wheels and tires are the lower production cooler ones. They are more desirable from the collecting point of view for being fewer AND better looking. I don't want any of them from "my" point of view
