When you see the base C6 beside the Z06, it becomes obvious that the Z06 is how the car "should" look. It's a shame that they didn't offer the Z06 body with the base car as I think it would have greatly improved the reception the car received. I just can't get used to the wide wheel lip openings on the base C6 body...the flared fenders and small wheel lips are much more appealing.
I agree with your comments on the C5 also - I hated the car when it first came out. However, I fel in love with the lines of the C5 Z06 just as soon as I saw it
