Prices tend to follow the condition and options. Original rust free is a big plus---so is 350, auto, air and all the cst options. Good drivers tend to start around $1500. and go up from there. Full restorations are priced according to the extend of detial and the quality of the work. Most i've seen were non-professional driver quality and priced around $5,000.+-
I have been looking for a solid driver with original, no rust body. Will probably wind up having to buy one out of california to get what I want.
Hope this helps.
