I have spent two weeks with my x5d, black sapphire metallic / cinnamon brown, and i just took my first road trip - to Lake Tahoe. What an amazing vehicle!

I optioned the car out very similarly to what you are planning to do... and I have some feedback for you:

1 - I got the Sports package with the 19" wheels and Adaptive Drive. It's amazing - like a magic carpet ride. I can't wipe the grin off my face when I am driving through the twisties in the mountain. I don't think you listed AD in your list, but consider it... maybe try to look for a demo with and without the feature. I'd opt for this combo for the driving pleasure, no question.

2 - definitely get the Auto high beams - they are fantastic and very useful. Don't think twice about it.

3 - I'd get rubber floor mats, not carpetted. Certainly not for the winter. They look great, especially in a black carpetted footwell (by the way... I thought about this too late for me, but it's probably cheaper if you go to the parts department and get the mats with a 10-20% bmwcca member discount, rather than having the salesperson just tag them on to your order. I know it's not a big deal... but as a matter of principle this shaves off a bit of the excessive cost of something that should be included in the car anyway)

4 - if you're planning on loading anything grimy or muddy in the trunk, get a rubber trunk liner. The bmw reversible one is very nice, but also very pricey.

5 - i have the side-view cameras... they are not worth the money imho. It's a toy that I don't foresee using much at all.

6 - I have the multi-countour seats and love the adjustability (even though I don't care for lumbar support). My E90 had sports seats - and these are a notch above.

7 - My opinion on the color - go for the space grey. I find it super elegant (in my case, my wife veto'd grey, go figure). Black looks great, but it's truly a pain to keep up.

8 - I got the smartphone integration (iPhone user myself), but frankly, I fail to see the usefulness of the package. Skip it.

9 - Last - rear climate. The main question reason i didn't get it were the tinted windows in the rear. I like the look with all windows clear. I think the rear climate adjustments are cool - especially if you have older kids (doesn't sound like you do). Had the window shades on the E90 - they are really useful actually, but in that application the main use was the rear shade. 50/50 on this one.

I have an opinion on every item you list... as does every member here, I am sure. One last item - comfort access: very, very cool. Good choice!

I think Oyster is the absolute coolest looking interior you can get. Great choice there as well.

Good luck!
