Overall it's just a great car, rides well, always works as it should, Once you get to know iDrive it's a good system but not great, quality fit and finish inside and out, comfortable on the highway, in traffic, or on the twisty back roads. Decent MPG for a large car with a V-8, average 16 MPG, (80 city, 20 highway driving). Can be had at great price right now with slowing sales and a new model coming out soon, if you don't mind driving the older model. Can't beat BMW's warranty and free scheduled maintenance.
Great engine, smooth transmission, comfortable front seats and interior, smart dashboard design, balanced ride, sharp handling.
iDrive controller and display (revised in the 2009/2010 7-series), Should be Standard for 80K luxury car; Adjustable Suspension (ride pkg), Comfort Access, and Premium sound Pkg, iPod Interface. BMW bring a diesel and Xdrive (AWD) model to the US immediately!
