But surely you mean "CAD modelers/animators" instead of "gd's".
I think Chevy's got a tough job on their hands, if they're trying to live up to the good looks of the C6.
The things i don't like about the C7 (if the renders/models are anything to go by), is that rear flank and rear wheel-arch... the wheel-arch so needs a bit of blister or pronounced lip (like the C6 has), i feel the area behind the rear wheel needs a bit of a taper as well, strictly speaking, it's not a flat area but still manages to look slab-sided like a GTR at the rear... i think people will maybe get used to the rear quarter windows though, they kind of have that upwards kick to them like the old 70's Vette (forget which exact yr), where the door used to meet the rear buttresses (maybe it's just me that's seeing it *shrugs*), and i agree with pretty much everyone else with regards the rear lights.
If it comes out like those renders/models it's going to be pretty awful imo.
