The X5, like most modern BMWs, will slowly fall apart around you. Our company director of engineering for some reason owns two late model X5, I am appalled at the multitude of build quality issues that I spot when I ride in it. Many creaks and rattles, cracked clearcoat on the wood trim, cracked plastics, idiot lights, etc. The Audi may have electrics designed by Lucas, but at least it will still look nice at 100k. The Cayenne is actually pretty solid, especially the newer ones with the metal coolant pipes. The Ranger Rover is a Range Rover, enough said. Just Google "Doug Demuro Range Rover" for some good reading, and buy an aftermarket warranty.
