@Raza, regarding the Panamera, all I can tell you is I had the opportunity to take one on a track once (not mine!), and the car seemed to literally shrink at speed, to where you wouldn't believe it was a 4000 pound sedan. It was like magic. I also drove a 911S at the same session, and yes, it was more responsive and a bit more fun. But I think if you had the opportunity to track a Panamera, you would be very surprised...
