Who's adding the top and side cams?

Just curious who is opting for the Side and Top view camera on their M3/M4, I didn't see a poll for it. I have never had a car with these features, and I have read on some other threads how useful they can be in the city with parking (top view) and pulling into traffic with obstructed view (side view). I don't want to get the full blown drivers assistance package. It'll be nice to be getting the rear view cam with the parking sensors in the exec pkg, also new for me.
