maybe also because it resembles a ferrari
Convergent evolution in terms of design? It was bound to happen.
Whereas if you look at the 550/575 Maranello an the C6 you see a resemblance due to the headlights and the intake, yet the 550 came out in 96ish. And the 1/2 Gen Viper with its NACA duct looked similar to the 550, from the front.
Or is this a type of parallel evolution, whereas two related cars (Corvette being a front engine car, and Ferrari having a line of Front Engine GT sports cars) all being design with certain packaging, headlight (C3 Corvette started its flip up headlights, and the Ferrari 365 started with its flip up head lights), that eventually it was inevitable that they were going to look similar. Yes, they were going with more "sexy" for the Corvette, but sice when is it that Ferrari and Euro cars can only do sexy?
