Wow you haven't really limited iwhat you are on the fence about too much have you
.
Colors: like you said re-sale is important so you don't want something off the wall. That being said, I would go with Space Gray since you stated you don't want another black vehicle. Also, black interior will also be your best re-sale option and that Oyster will be nightmare to keep clean long term and will show signs of wear more than black in just a couple of years.
Opinion on some of your Options, etc: Definitely get Climate as the tint makes a big difference in the appearance of it as well. Sport pack with 20's--a must have. Multi-contour I have and they are great. As far as the venilated seats I would think that will be hard apply seat cleaners as that might be a mess (again, thinking long term). You didn't mention Prem Sound---it's definitely worth it (if you like music). The carpeted floor mats--just talk to your SA and have them throw them in for free that is kind of a "BMW tradition" when you buy one.
