Wow, that's close to even. I'm glad this popped back up, I lost track of it. I went back and re-read the posts. One of your posts Bryon caught my attention. I'm surprised that out of 20,302 Z28's produced in just 69 alone that you only have 1400 in the registry. I would have guessed that number to be much higher.
I also have been wondering, could it be that possibly RS cars are more likely to be saved by collectors as to the reason why we have almost an even number split in the polls between RS and non RS? That might skew the numbers a bit.
