It's $4750 if you get it with the front + rear PDC. To be honest it's worth it.
My opinions on each individual options:
-Auto Dimming Exterior Mirrors - Not that important
-Glass Sunroof - It's a personal opinion but I prefer having a sunroof. Can tilt & get the air flowing through the cabin easier is a nice feature in this car.
-Auto Dimming Interior Mirror - This is not too important either
-Through Loading System - Is a nice to have especially if you ski, or take long drives often with passengers in the back seat to reach for stuff.
-Heated Steering Wheel - Is a nice winter feature.
-Instrument Cluster, extended - I would definitely want this additional info on your dash
-Electric Seats with Driver Memory - Good for multi drivers, or if your car goes to the shop and they adjust the seat while taking it in for service.
-Park Distance Control, Rear - Great feature to have
-Park Distance Control, Front and Rear $450 - This paired with the rear camera gives you full surrounding warnings and also the Park Assist button to manually enable/disable the feature
-Rear View Camera - a must have, for parking and worry about backing up with small children
-BMW On-Board Navigation - a nice feature to know where you are and worth it since it includes the 8.8" screen for more crisp detail and larger space
-BMW ConnectedDrive Services Package - not applicable for me...
