That is absolutely gorgeous.
I had an '85 Z and I paid 12,500 for it at the time. It was a year old and a GM brass hat with 3000 miles, I believe sticker for it was in the neighborhood of 16-17k. It only had cloth interior though, no power windows or seats, it had a/c. It would certainly be amazing if you get close to the price you're asking for, it must mean that the Camaro's in this condition are starting to gain value. GLWS
