Missouri is full of vintage cars and trucks that have rotted to the ground... and it is sad...
maybe wait a few months, drive back and get to know the owner... ask him why he bought it,
what does he intend to ever do with it.... get him to thinking about it... Just don't be the guy
who gets him to think about it then he sells it to the next guy who stops and ask about it....
Happened to me I stalked....er... stopped by a older gentleman's gas station about once a year and asked
about the 2 tokheim 300 gas pumps he had, that he wasn't using.... was never gonna sell them...
4 months later.... he sold them....
hang in there!
