* I would ultimately like to change the music without getting out of the car, so the glove-box changer works great for me, but I've heard BMW had some problems with it. Is it true? Am I better off with the one in the rear? Is there a way to install a non-BMW player/changer? I am in love with the new Sony player, but with the NAV system, there's nothing I can do - no more space in dash.
* I like darker trim, I think it offsets sand leather better, but I hear that it is so dark it seams nearly black and looks more like plastic than wood. Should I go for the light color trim? Dark looks great on all photos I've seen.
* Are Xenon lights and self-dimming mirrors really all worth the money?
* I am going for all packages, premium sound, Park Distance Control, auto, and NAV System on a 3.0i. Anything I forget that I really should know? Or something I got that is really not worth the money?
* Finishing touches like matts and so on: anybody bought any non-BMW ones? $130 seems a bit over the reasonable. Which ones to get and how much should I expect to pay? Same question for seat covers. I like the sheep-skin, but $495?!!!!

Many thanks!
P.S.: My last post is still unanswered. Anyone knows how to get the DME version and to ensure it's the latest? Thanks.
