I agree with you '12's are not a good choice at this point. Actually they should be offering more than 10k to move them considering the large profit margin on the 6.
Interesting note - USAA current discount on a Imola/Ivory 2013 650 coupe optioned with my specs ( M sport, LED's, Exec Pkg, 373 rims) is already $13,500 of list. Pretty good considering early in the model year. If I can combine this with a year end incentive should be a excellent deal. My only issue is wanting the Idrive update which kicks in with March builds. Have to see how it plays out.
Still conflicted on the B&O - really want to hear the system, no 6 around has had it.
