Well the Cayenne can run up in price. However the base 290 hp engine with the manual 6 speed is cheaper than the base X5. With automatic it is only $500 more. Of course in the Porsche you get leather standard as well as a very large list of features that would cost more in the X5. Not to say the Porsche cannot be optioned into the sky, it can be obscene if you get carried away. As far as gas guzzling, it is about 1 mile per gallon worse than the X5. The new Cayenne is vastly different than the old T-egg clones of years past IMHO. The X5 is larger and can have three rows of seats so if that is a consideration the Q7 is a closer match. Again, it has more power in the 3.6 engine and is cheaper than the X5. Lots of choices! As far as "snooty service" you can get that with any dealership. The worst I ever encountered was a Mercedes shop (since gone under I might add). My Porsche/Audi service is very accomodating and equals the treatment I get at the BMW store.
