Don't forget to check for rust issues. I once looked at a "B" for a very reasonable price, checked the underside, and the rust damage was severe to the point where I wondered how things didn't shear off. All bolts were covered with rust, and the paint had bubbles in it on the bottom of the van.
Found out that the van was stored for most of its life near the beach, then hauled to Texas to be sold. Since most Texans don't factor in rust issues unless they are from Houston, I'm sure someone else has already bought it.
