I am not one to call photoshops but I would have to agree with SupraLB and say that is a horrible photoshop. Look at the rear brakes and drivers window, it's so obvious. If the windows were tinted you wouldn't be able to see through it.
What is this, Rx7 Club? I usually see these harsher critiques elsewhere...
Yes, perhaps it's a photoshop, but if you ignore the "Fake"ness of it, it DOES in fact give you an idea of a z06 with black rims and tint if you wanted to go that route, which looks quite awesome to me...and I'm the elitist!
I think some of you need to see this car in person. I had the same reaction/impressions you all had but seeing a nice yellow z06 in person at the NYC auto show impressed me. It just needs black in the headlight housings no matter what color the car IMO...to look better/good.
