I would not take a Pontiac to the "Ford & Chevy" (Barrett Jackson) show. They never seem to get a good buck there.
You need to have someone look at the car for you that understands these cars (and take 150 pics) or fly out to see it yourself. I have been looking/watching for 3 years now. That car "appears" to be a very good find but the condition needs to be verified (and paper work etc.).
I bought my 68 400 HO vert based initially on a one line ad in Racing Junk!
Worked out great for me.
