2007 BMW X5 SUV 4.8i 4dr SUV AWD (4.8L 8cyl 6A)
3rd & last
 My 3rd & last BMW (two 7 series and this X5).  With 1300 miles on my 4.8 X5 it had to be towed to shop while I was 800 miles from home when the electronic transmission would not shift.  Computer updates were no help. As I write this from my motel room after 2 days of waiting, the factory folks are still scratching their heads.  Other than the reliability issue the car is very rough riding.  Wind noise is too pronounced for a luxury car selling at this price point.  The ventilated seats are superior in overall comfort to the hard buckets which are standard.  The runflat tires cost abt $500 each to replace and should be an option not standard!
