I love my brother and Jacks Z06s but if I was going to buy a daily driver right now it would be the older CTSV and I would paint it flat black and Drop it on some 18inch CCWs (C14s http://www.ccwheel.com/files/wheelprofiles.php)

Maybe do heads cam and a kit....call it a day
Theres not much you are going to run into on the road that will hang with that.
