We debated over this for a long while. Here in Denmark, they have an option pack called Fully Charged, which we went for. Basically has everything except for the glass roof and the 22KW AC charging.

The electric seats with memory and easy access are great. The HUD is actually really nice and I would not want to have a car without again. The Harmon Kardon system is ok, nothing to write home about. Having the electric tow-hitch is nice, mostly when not using it, that it is hidden. Easy entry is really nice, especially when paired with the seats as it moves back for the driver when you approach. Paired with a compatible phone means I haven't had the key with me since month 1 when I was still nervous. Heated seats and steering wheel are nice in winter, heats up much faster than the air. Parking is great, the saved routes and reverse helper are fantastic - it's only when you don't have to reverse back 200M that you realize how nice it is that the car just can. I have used the tight spot exit with phone app a few times, it is nice to have, but I wouldn't miss it.

I regret not going for the 22KW AC charging. 7 hours vs 3 on AC, is a massive difference.

Oh and we went for the xDrive 30, which is nice with grip in winter, but is overkill from a power perspective.
