I'm guessing that 90% of the 2013's ordered by members here (and a similar percentage of other "orderers") are for M-sport versions. Also, if you look through Autotrader etc for 2013 models currently for sale, around 70% are M-sports which means dealers are ordering them as well. Basically, for inventory it's either base 528 or M-sport 535/550's out there. There is no question the M-sport front and blacked out trim/headliner better steering wheel, etc are worth the cost but we are still not sure if there are actually different springs now. Regardless, since there is no more "sport" option at all most people are getting M-sports now.
EDIT: .....also BMW has whored out the "M" logo all over these things to an embarrassing point, I think they learned that from their MBZ friends. "IS THAT AN M5?" NO "WHY DOES IT HAVE M LOGOS EVERYWHERE?" I Don't KNOW
