Yeah, but it sounds really, really good. If you were in CA you could listen to it. I get that it's really expensive, but I would rather spend the extra money now and not have to mess with the OEM stereo later. I.E., I don't want to cut and splice into a $60k car so get the Premium sound from the factory.
I would actually delete Cold Weather Package unless you need the folding rear seats and headlamp washers. Just get heated seats as a standalone option. The fold down seats add ~20 lbs. and a hole in the shelf for the folding feature (I believe). I also don't like the look of the headlamp washers. I'd rather just clean the car myself.
