Before i ordered my 2011 5.0, i drove both the M sport and a reg 5.0. Huge differance in handling. I felt standard was too soft for the new motor. Yes my 2008 current 4.8 is loaded with Nappa and goodies but the pricing on the LCI is higher for a comparable X. I opted to give up some of the goodies for the Msport, which just made more sense if you want the adaptive drive. Also, ive had Black saphire Bmw's for 10 years now and wanted a change. My X is in production (paint shop) and is scheduled to be finished on Friday.
