Just to bring it back home, when I was shopping for a used 4x4 SMB, I contacted several of the owners of the ones listed on the SMB site. They all were willing to negotiate a little, but not much. Each of them sold to others at what I'm guessing was within a few $k of their asking prices. Now that I own one, that's a good thing. They definately hold their values. Restored VW Westy Syncros are approaching the same price as many used SMB 4x4s, so that provides some insight. Its a strong market for these rigs....out West
What worked for me was going East, young man. The market in the central states is not what it is here out West for 4x4 vans, especially when you start talking about the sourthern central and eastern states. Heck, people drive 2wd Expeditions there. Good luck. Take your time, or not. I decided I needed a Sportsmobile in mid-January, while in Baja (was drooling over one at Cabo Pulmo). Then, I looked them up on the Net. The prices blew my socks off. A mere six weeks later, I had mine, for a reasonable price.
It takes a village to raise an idiot.
