its all about what you want. if all you car about is power, z06. interior looks exactly like a transmarobird, which i think is really fugly to begin with. c6 interior is hott though.
z06 is a great car, does wellon tracks, etc. i’m not so sure about that rear suspension, but i’ve never driven one more than 15 mph and their track times seem to be good. but damn, that interior blows.
i view a weekend car as something i can drive a long distance. take your lady to a wine tour 5 hours away kind of thing. or just go blast the curvies alone. i like both cars. maybe i’d go z06 and put in a c6 interior (interior doesnt really matter, its just that the c5 is so fucking fugly)
