Ed,
VERY cool GTO. Love the color- and love seeing unrestored cars. I have a unrestored 67 convert also, was going to drive it to Bloomington last June but a family emergency came up and had to skip the show. Check it out:

Fun to compare the details, like the original rear window codes, etc.
Best of luck with the eBay sale.
