I bought a 750li and so far I have 20,300 miles with no issues at all. Mine has all features including premium and sport package and I optioned for different M styled wheels and mine is alpine white with tinted windows.
Ride, handling, reliability so far, build quality, technology, love the night vision, and pretty good fuel consumption for a larger sedan
My only con is how easy it dents. I hit a buggy at the super market and it gave my bumper a microscopic nick.
