This is my second X5. My first one was a 2003 and I loved every second of the three years that I drove it - 36,000 miles. It is quiet, smooth, a ball to drive, and just the right size for my needs. Also, it gets surprisingly good mileage - the on-board computer calculated my three-year mileage at 21.0 MPG! I was so happy with my X5 that I did not even consider another vehicle when my lease was up. I signed another three year lease last December.
Styling, handling, quiet and smooth ride, fuel economy.
