1965 Corvette Mako Shark ii Concept

VS

1968 Corvette C3 Stingray 427

Don't mind the lady in that picture.
P.S: I vote for the Mako Shark

Fact: The C3 Stingray is actually based on the 1965 Mako Shark ii Concept. It's a car design by Bill Mitchell. In 1968 the Mako Shark was redesigned and named "Manta Ray".
