If they're like typical military "disassembled" surplus that means they've been demilled. In other words, cut into quartered sections by a torch. They used to do that to jeeps. You can get surplus Humvees and there's several web resources. Check out the MVPA as a good place to start. All the units I've seen are in the $10K to $15K range.
