I was with my brother when he stopped in at a lot to look at a used car. He noticed a truck that was headed to the clunker program. Still looked good, mid 90's pickup. He wanted the tires which still had a lot of tread left. Salesman didn't care if he were to swap them, but didn't think his boss would allow it. It's this kind of waste that just irritates me. Had people brought in last-on their-leg cars, I wouldn't have had as big an issue with it.
