I don't know the guy, but I've driven past the yard many times. According to one of the ads, he's moving, so he's selling everything. I have to imagine there's probably some interesting stuff in there - there were a couple of Porsche 914s in front for a long time. A sample:
1938 Chevy dumptruck - $3900
1989 Corvette 6spd with SCCA history - $4500
1983 Toyota 4x4 SR5 pickup - $3000 (not 100% sure this is the same guy, because there's no contact info in the ad, but I suspect it is)
