That's the thing only a ferrari should look like a ferrari and a corvette a corvette
If I'm buying a vette I DON'T want it to look like a ferrari
C6 was much better looking...
think of it as convergent design. Look at how similar C6 and Ferrari 550/575 looked in the headlights and hood vent at the front. By the time the C6 came around, flip up lights had been eliminated. They are too heavy, and dirty up the air (the NSX got rid of flip up lights, and the Diablo went to 300 ZX headlamps previously).
Both the C6 and and the 599 (both bowing in 2006, I believe) are front engine GT/sports cars with heavy bottoms. And were criticized for that look. even with the black at the bottom of the back, which would break up the heft. Even the C5 and 550/575 had heavy bottoms, and similar round lamps.
Now look at the F12 and the C7, both are sleeker, still with phat booties. I don't think that GM intended to make it similar, it's just that the design envelope is damn nearly the same---long hood, two seater, short deck. Need cooling vents and air flow. LED lights. Better quality interior. Corvette had to step it up in that department. And it's getting noticed.
Think of it as the Z06 and the ZR1 means it has arrived to the party. The C7 means, it has come with the right jacket this time.
