Not to hijack this thread but as we are talking about wheels, a good way to get nice cheap wheels is to wait for someone with a C6 to upgrade their wheels, then buy their wheels from them. I have seen nice factory rims with rubber for under $1000. (not new rubber).
In that thought, Manny, have you seen the C6 "Gumby" wheels on a C5? I found a set for $510 plus shipping. They have scuffs but I would still like to know how they look on a C5 before pulling the trigger.
