2007 BMW X5 SUV 3.0si 4dr SUV AWD (3.0L 6cyl 6A)
Traded in the Porsche
 Traded in a porsche CS for the X5. The X5 is perky but not as fast as the CS. The X5 is nicer to drive on long trips and has features like bluetooth &  ipod. Tire wear should be better and cheaper. The iDrive is a breeze to use as is the voice command function, very cool. Great suv but do your own homework.
