Very hard to find a 6-speed in M-Sport guise, but you could always retrofit the aero package to at least replicate the look. N63 customer care package would apply to any owner as long as the service has not been performed yet. I am with you on opting for the RWD. Unless you live in an area that gets a ton of snow for more than 4 months out of the year, I don't see the point. I want my Ultimate Driving Machine to be rear wheel drive with the silky smooth inline 6 that BMW is known for. I guess that gives you a hint to whether I recommend the 535 or 550. Good luck with your search. I had my heart set on an Alpine White with Cinnamon interior, 6 speed M Sport, but had to quickly give up the 6 speed dream as inventory for pre-owned M-Sports was very limited when I was shopping for mine (early 2013). Fortunately I don't miss not having a manual one bit. The 8-speed SAT is that good and frankly, the F10 is so big and luxurious, it just feels right to have the auto. Just my $0.02.
