i had a cayenne turbo before i got my e70 x5 ... and i really hated it ..i agree with everything that topgear66 said about the car... its the worst suv i have ever owned or driven.. .. the cayenne rides bouncy , if u step on the throttle the gear changes like ur in an ferarri, the car rattles, highway noise is verry annoy ... and i have never spent 2 weeks straight without bringing it to the dealer ... imo the x5 is simply the best in its class ... and i have tried every other suv ....
