Saab 9-2x - Car was an auto and extremely laggy but I really like the mild dressup they did to the interior. Car seemed to handle very well.
From the little I've driven a WRX, the 9-2x felt like it had slighty less bodyroll than the WRX.

Quadrasteer GM trucks - still partial to the Titan on the fullsize truck lineup put the turning radius on those with the quadrasteer was amazing.

CTS/STS - Very nice IMO with decent power although the G35 sedan was for some reason missing from this comparo


C6 - Course didn't let you get a great feel for the car but around the one turn they gave you it felt like a slot car with near zero roll or flex. Pedal effort on the clutch was surprising....required barely more pressure than the clutch on my Protege5.
