New BMW Guy 
2010 BMW 5 Series Sedan 550i 4dr Sedan (4.8L 8cyl 6M)
550i with M-Sport Package
 There is no other way to buy a 550i. The M-sport package is a must. The wheels and more aggressive styling gets everyone's attention when you drive by. The Logic 7 system is the best sound system I have ever heard in a car. The growl when you take off on the highway is euphoric. The heads up display is awesome especially when you get the nav directions on the windshield. I now know why everyone who owns a BMW will never own another car. The hard drive lets you burn your CDs and lets you hear your favorite music instantly - no waiting for tracks to pull up and better than my Infiniti hard drive system. The updated iDrive is very quick and intuitive. Bluetooth phone connection is impeccable.
