I read the C&D Z06 v Viper last night. They mention a chassis that doesn't know how to communicate and snap-over-steers. Also, only qualified drivers should be handed the keys.
I've read that the new Delphi stability-control is not as intrusive as before. I'm not sure that was a real good idea for a 3,200 lb. 505hp car. You would think that in this litigious society they would have done the opposite.
Personally I like it and will own one when GM gets the bugs worked out and the price bottoms out. I paid MSRP for my 02 Z06 and won't do that again.
There are strong rumors that GM will SC the car to over 600hp next. That will be the vette for me. BUT <---big BUT, I will respect the power and responsibility that car will require from day one. I only hope immature, irresponsible drivers don't end up ruining our fun.
