Is there a specific list of colors available for ordering or the cost? Audi has a brochure with available colors making it easy, not sure if there's one floating for BMW. A different question is are the long term running costs for a 550 vs an M5 that dramatically different? If ordering individual I'd want to purchase and keep for awhile, and as special as the M version is the performance gap has narrowed considerably.
