Appreciate all the replies. I guess I should have given a few more details. Not trying to cause an uproar. Looking for a value guide to give me a rough idea on a fair reasonable value. I know fair and reasonable are relative terms. There should also be a guide for sentimental value! Everyone wants to get the most they can out of something and pay the least for something. Myself included. But we have to be realistic also. Anyway, I'm looking for a 1966-69 GMC w/V-6 or a Chevy '69-70. The prices I've seen are all over the place and it might depend on the area. This is the reason for a price guide of some sort. I've passed on a couple of decent trucks that I thought were high and with a guides help, maybe I won't make that mistake again.
