I think that is where GM was headed with the corvette. I'm not sure how well it handles, i'm sure its no slouch. Not many people have got there hands on them yet. 500 hp..3100 lbs is sure to be a killer combo if you can put it to the ground, and keep it on the ground.
Every car has there problems. And if they are indeed releasing a new cobra, im sure it will have its problems too. When they first came out, they were blowing the trannies to pieces. It is also my understanding that every single one of the new gt's was recalled, because the wheels werer literraly falling off of them. Vette has had there problems too.
Also, something you guys may be interested in, according to the lightning owner assoctiation and a few other places, there may NEVER be another lightning. And the cobra is going to be pushed back to 07/08.
