I am wondering. If I really really wanted a Z/28 convertible, or a Z/28 automatic or Z/28 with AC, could I have gotten one if I was willing to pay a premium or sign off that the AC would not be warranted. I suppose the issue was never tested because if you really wanted these items on a sporty Camaro, you just got and SS instead. However, they did build that Z/28 convertible for Pete Estes. So, I had a time machine and walked into a dealership and plunked down the full sticker price and say an additional $500 for "convenience", could I have gotten a convertible Z/28?
I'll bet if I went to Gibb Chevrolet at the right time I could have gotten him to change one of those 50 ZL1's to a convertible RS with JL8, power windows and factory AC. Tell me I'm not the only one that would do that if we had a time machine.
I can only think it never happened because no one really tried.
