A 1999 or 2000 C5 FRC compared to a 2001, 2, 3, or 2004 C5Z06 would look about the same since they both have trunks. The side brake duct screens would be the most noticeable difference.
A C6 compared to a 2006 Z06 would look different because of the hood scoop and flared fenders on the Z06.
In both cases the grin on the Z06 owners would be bigger than the grin on the regular C5 or C6 owners.
It depends on whose grandma it is too.
