Getting very close to ordering my new car, I know I want to get nav, premium, cold weather, and rear climate pkg. I am not sure about the sport pkg, is the ride much stiffer than without the sport suspensions? Also I am thinking to get the comfort seats, I have tried both the sport seats and the comfort, and I can't make up my mind, it's difficult without actually driving the car for a straight 8 hours... Any advices would be greatly appreciated.

Also are the rear side airbag an option?
