We had some junk in the shops yard last year. Got 300 a piece for junk some with no motor, I also had an old RV that I lucked out and sold for a couple hundred bucks for. In commerce city there are guy driving around asking everyone with junk in their yards if want to sell. They start low but if you hold your ground you get more. I'd imagine if these guys are giving 3 they're at least getting 5 hundred.
