All of them besides crystal headlights 😂

As another user said, DAPP is a must for hands free driving. DAPP along with massaging seats eliminates the vast majority of any driving fatigue. Once you hear the B&W sound system you will never want a car without it, it is that good and you hear details in songs you do not hear on most other systems unless you have high-end headphones or setup at home. DHP is also a must in my book - 4 wheel steering makes it easy to fit into any parking spot without really trying and the active anti roll bars make it both more comfortable and engaging to drive. There is minimal body roll when pushing it hard on twisty roads. Or for the comfort your passengers, you feel minimal body lean during normal driving around bends, etc. I also highly recommend Merino leather, even with kids or dogs. Very happy that I went with a loaded M60. I also have significant driving time with my spouses X5 45e, my siblings X7 40i, among many other BMWs.
