Interesting what you said about the axis of rotation on the GT2 and having all that additional mass back there. Makes sense. I've driven a couple on track but never for long enough to really get familiar with the car.
Also understand what you are saying about the expensive and complicated motor. I sold one a couple years ago and Porsche dinged the car based on how many times the motor had been taken to NEAR redline. Mind you not too or over, but close to redline. They said if the motor popped they would potentially not cover it. Took a while too sell because of this.
The 996 GT3 was and still is the most fun vehicle I've ever driven on track. It's the perfect blend or power, control and feedback. I keep my eye out for a deal on one but alas I don't think they will ever get into the $50k range.
