I really am into my new '06 750Li. It's got great styling ('06 is a definite improvement over the '05). Its got lots of power and hi tech gizmos. Driver's massage chair is a nice feature. It's also got high quality feel both inside and out. And it drives like a sports car, even though its amongst biggest sedan on road. Oh yeah, its road presence is another good feature. This car stands out in the crowd. Better overall package than a MB S class or a Lexus LS.
Comfort seats, bluetooth phone, big V8, sports car feel, road presence, and dare I say it -- Idrive.
None, but I would always welcome more horsepower.. Maybe 500hp will become the V8 norm in years to come...
