Very in depth and I am impressed with your efforts. Of the 5 listed in orange the one that caught my eye was the 2nd on the list. The third has an undesirable body styling, for lack of a better word =). Also @ 76K miles make sure the 60K was done and you should have a reliable (hopefully) car for quite sometime while you get acquainted with the Z world. I would recommend replacing the aging tint but as long as everything checks out mechanically and cosmetically that would be my choice. Good luck and welcome!
