I would deffinately agree on buying the books to make sure ur not getting swidled. And pricewise the best thing to do is just look around, and more importantly ASK around, there are plenty of cars out there that are not advertised for sale but would probly be sold if someone offered to buy them. Mine was an isolated case but my uncle had my car for like 20 years and only drove it for the first 5, then it sat and sat having parts picked off it here and there and sold when he needed money. Well it was my dream car, so one day i just asked him(knowing it was a longshot), u ever gonna do anything with that car, or u wanna sell it to me, a relative that will apreciate and drive it? Well he gave it to me for $800, '69 RS/Z28, needed engine, tranny, and steering column. Still needs misc. interior parts, but its mechanically sound, and fun to drive for about 2500 i have in it. So yea just be patient and if ya happen to see one sitting somewhere, go ask the owner, the worse they can do is say sorry not for sale.
just my opion. Jon
