Why do people do this? Waste!

there is guy in the next town who hordes 70/71 Darts, among other things. Maybe about 6 of them. I stop in everynow and then because I would be interested in a nice 70 valiant and the 70 swinger he has. He won't sell me the Valiant because he thinks Hemmings is coming to do a feature on it, having factory tinted windows and stainless trim-4 door Valiant production probably 200,000! He also doesn't want me to drive it in the winter (which I would) but it is ok to just sit there and rot. So I asked him about the swinger (each time I stop it looks more tattered), That's his daily driver he claims and then the daughter asks him when was the last time it was on the road--3years ago! Money sometimes doesn't talk, he just can't part with anything.
