For those who doesn't know what a Centennial Edition look like, here's a few pics. The window sticker price was just over $90k for the one I was looking at.
Really could have gone either way. The M3 and Z06 are totally different animals but both have their merits. In my case, they were so equal when I weighed out the pros and cons that it really was a coin flip. I could have very well had that Vette in my garage right now and have the same level of regret. That Centennial Vette was the only one I would have gone for though as far as C6s are concerned.
