Wow, i guess i wasn't the only one lucky enough to find an M Sport wagon! We just found ours a couple weeks back 3 hours outside Seattle. Its a 2010 M Sport in Le Mans blue with roof rail delete and nav. My wife and I absolutely love the wagon (except the low front bumper...still getting used to it) and hope to put many more miles in the coming years.
If it were 100% mine, i'd wish for the 6 speed manual but had to compromise since its the family hauler.
Congrats on the find!
