just sold my 2008 M3 in Dec for a 550i x-drive m sport. For about $8000 added Dinan S2 performance chip, Dinan suspension, and Dinan free-flow exhaust. Now the only thing I really miss from the M3 is the double clutch transmission. But this baby flies and has waaaaay better torque feeling with the all wheel drive than did the M3. You'll get over it.
