why does no one sell?

[chevy406]

well to start off the other say i was driving around the not so nice part of the city i live near serching for parts and found this yard full of trucks and some things i wanted (like the box and 68 front end in it). so i go knock on the door the guys wife says she'll have him call me, a few min later he calls me i talk to him for a bit and he says he is restoring some trucks and cant sell them even though the guy at the business next to it said that the parts have been there for as long as his shop has been there which he said has been about 10 yrs. this is about the third or fourth place like this i have found and people wont sell the parts they seem like they would rather say they are "restoring" a truck and watch the parts rot away! it frustrates me a ton! sorry for the rant but was wondeing if you guys have had the same problem or maybe a solution to it.
