I don't understand this thread at all. The Corvette is selling relatively well, if it wasn't then Chevrolet would discontinue it. It's pretty amazing that the car has survived this economy. Most younger people can't afford this car to begin with, it's been like this since the car was introduced in the fifties. There will always be a percentage of the population that salivates over the Corvette, well I'm proudly one of them, but I didn't buy my first brand-new Corvette until a couple of years ago, up until then I could only afford to buy used ones.
Competition among sports cars has produced a pretty amazing C6; this is by far the best car i have ever owned, and the best corvette ever. It's quiet, powerful, easy to drive, has plenty of storage, excellent visibility, great gas mileage, killer looks, in short the engineers have done something that one would never think possible: they have created a Corvette that you can drive every day. This car easily matches or exceeds its competitors in so many aspects that it sells itself, I think it was a smart move for Chevrolet to create the Hertz rental so that people could try it out; I simply can't imagine Chevrolet ever having the confidence to have tried this in the 1980s with the c4.
In short, the car is an excellent product, and to suggest that younger people aren't interested in it is an anecdotal observation specific to your particular circumstances; every time I drive anywhere in my c6, it is stared at by dozens of people, young and old, and I can't count the number of times that people have come up to me at gas stations to talk about it.
So here's to hoping that the Corvette will be around for a long, long time.
