I had a 740, 745 and now a 750. While I enjoyed each of them and stayed with BMW, the 750Li is even better, by far. It's as though my 745 went to the gym for 6 months. Tighter, faster, smoother and easier electronics. I looked at MB 550,Jag Super V8, and Audi 8. All were much more money to lease (BMW hs highest residual) and each is a great car. The 750 is the best of the best. So far, (2500 miles) no issues or problems. It even looks better.
Comfort, power and convenience
Include the phone adapter as part of the car, not an add on.
