 I never thought of leasing a BMW, but someone very close indirectly recommended it to me. This is my first experience with a BMW and so far (first month) it has been very good. The xDrive system is quite good on ice and snow, but as other reviewers have commented,  a delay in acceleration can be felt. Fuel economy is around 16 to 18 mpg in town and 28 to 30 on the highway. It may be too early to comment on the run flat tires.
