I have been in the 76/7
I have been in the 76/77 GTB market for two years - finally found the one. In my area (Connecticut/NY/Mass) EVERY one I have seen that SOLD for $27K-$28K needed some sorting out mechanically, not in the best cosmetic shape, modified, missing books, history etc. These buyers wound up putting another $2K-$3K into them. Concours, low-mileage cars were selling between $34K - &35K.
Mine is an honest-to-goodness all original (except paint), intact example. I paid a little more for it because mechanically is was completely gone through (carbs, ignition, belts, hoses, brakes, etc), rare color, rare interior (no radio installed)and met my expectations in this way. The paint is by no means show paint, but it looks great. Because there are few good early GTB examples out there, I have found there is always a trade-off.

Peter usually gets in carbed GTBs and has a black one right now.
