I don't know what to think about that write up. As far as different models they already have it base/Z06/ZR1, and the ZR1 stack up against higher priced performance cars along with being very reasonably priced compared to Ferarri Models.
Its probably a good thing that the base models are priced where they are. If you have the money to dedicate to one, then you also have the ability to make a good decision about whether this car is right for your life at the time. If the car was say 35-40k how many college grads would go out and buy one with financing for X years only to end up married and getting ready to have kids before the thing is even paid off. At least with our camaro's you can put a baby seat in the back if you really need to.
But if they want to sell more corvette's it might work, it just seems like they would have to sacrifice a lot of performance to reduce the price considerably and then it just isn't a corvette anymore.
