I like plain black look myself, you made a right choice, but the aluminum trim interior for me is the best looking, when i get my e70 and if it does not have aluminum trim i'am replacing it, dont like the wood in X.
WHich do you prefair? this might be a stupid question to you because you already got m package but, what do you think about the aero kit?
