Nice car
 No major issues with the car in 4 years.  Bridgestone run flat tires started "cupping" at 16,000 miles creating more noise.  BMW gave 50% discount on new Continental tires which are holding up well.  The run flat tires have a harsher ride than I would like.    Fun to drive and gets around 22 MPG in the city and around 30 MPG on the highway.  Great brakes.  BMW free maintenance program works well and oil changes and wipers are replaced without complaint.   Only other warranty claim was to replace front door armrest where the plastic was looking tacky.
