you have 2 Ferraris in your post. The first is the new F12 Berlinetta and I will say I do see a resemblance. People said similar stuff when the 599 came out. But then you have the 550 Maranello, which came out well before the C6 vette.

i was lurking around fchat and saw someone telling a story about coming back to his daytona and a father and son were admiring the car. the son said to the father he didnt like it ecause it reminded him of an early 80's corvette. the owner then informed the son that the daytona had been out about 20 years before those corvettes were made.
if anything, chevy copies the lines of ferraris to an extent. hell they have admitted to it before as well.
you have to be a serious MURIKA' car homer to think the italians would copy anything we do over here
