Here is yet another one coming on the market...1972 GMC Suburban, 3/4 ton, 402 CID big block, 65,000 orig. miles, has most all the vintage equipment. Originally purchased from Apgar Ambulance in Portland, ad states it's from an unknown builder, any guesses here? If the mechanicals are good and there is not excessive rust, then this one appears to have a VERY attractive price IMO.
