i bought mine used,and didn't want the cold weather package,and agree about not needing the auto high beams.i love my sunroof,it only adds about 25 lb.,but the carbon roof looks great.mine came with the base hifi sound,so i upgraded the speakers with the bsw ones.

you can get a better sounding system for less than the $1900 for premium.i also didn't want nav/idrive,which you have to have to get premium sound.the carbon leather is beautiful,i just bought it separately,but i agree that it's a lot of black with black interior.
you'll enjoy the car,it's a civilized beast
