Picked up the '08 SS a few days ago, and I have to say it's pretty good. Everyone mentions the torque steer, and everyone that has mentioned it is right. This car will surprise you if you are not careful. The seats are firm, but do not "hug" you like a sport seat should, but then again, this car is meant to cruise, not for SCCA solo-D. Highway ride is excellent. AFM system turns on and off real stealth-like...and the fuel economy numbers for highway are stellar for this type of engine.
XM, OnStar, steering wheel controls, highway ride and power to spare.
When you rotate the tires, the air pressure sensors have to be recalibrated, and it isn't very user friendly to do that. That is really the only issue I have with the car.
