Take it from a guy that got all the gadgets on the car, I only regret buying the BMW Assist.
The Exec package seems like a rip-off, but the surround sound and the lumbar support are great. Still debatable if I made the right choice or not...
Most people don't get the Driving Assist, but I find it invaluable and should be a standard option on all cars.
I can't see myself using an external GPS in this interior, wires and stuff hanging off the wind-shield is a bit of a turn-off in this beautiful interior. Hence, Premium package is a must. Not to mention the Convenience Package...
Head-up Display is also a cool feature to have. No more looking around for songs or directions or speed or phone, everything is in front of you... all the messages the car wants to communicate with you are in front of your eyes, in a 3D transparent glow... Awesome! Best choice I made so far!
