Ask him if he has any parts for sale, or to trade- and go there in a Mopar. Tell him about your junk and the idiots who try to pry the stuff from you.
People like this don't want to listen to offers when in their minds you are only trying to flip it for a buck and have no interest in the cars.
I know a guy like that, and good thing I met him when I was broke, because I wasn't asking to buy, only for help with knowledge and parts.
I know its not true for everyone, some people are just jerks, but I'm thinking most are attached to these cars and the value is not monetary.
The money to restore them is ridiculous, and guys like this say they will because that is what they are bombarded with- restore!
My brother has a 71 Challenger, and it sat for years because he was going to restore it- never happened. After much verbal abuse from me, I finally went over there and informed him that we were not going to restore it, but we were going to make it road worthy and start driving it.
Its ugly with crappy paint and plain jane tires and hubcaps, but he is driving it, and that is what really matters.
Go ask the guy if you can help him get one back on the road- looking as is.
