The problem Corvette has is it's buying public is getting older, a decade ago the median age of a Corvette owner was 54. Currently the median age is 64, it doesn't help that the publics perception of the owners is "an old dude going through mid life crisis" while wearing gold chains and loafers.
Corvette hopes to recapture some of the "youth" market with the new Corvette, unfortunately todays 20 somethings are more into non GMO foods, electric cars, and social networking than cars.
