Why do people do this? Waste!

Yea this is everywhere, I also know a guy here where I live who is strickly Mopar and had 3 challengers including an RT. He wouldn't sell and they all rotted away. He currently has a 67 Barracuda fastback, Plymouth Belvedere and a couple of more mopars. Won't sell, won't do anything with them so they will also rot away. SAD!
