I inquired on a truck in my nieghborhood awhile back. It was a 8 out of 10 92 reg cab W250 diesel with a manual trans. I thought this would be a $8000 truck(i wasn't looking so I didn't really know). He wanted $15K for it, I about crapped myself. It was only for sale for a week or so then it was gone so I imagine he got somehwere near that.
He must have some kind of connection because he has had two more nice ones since then and doesn't have them long at all.
