These cars are not my cup of tea...I wouldnt tow anything with any of them. I would take the FX50 and have money left over for a used M3. It cost 40% less then the X5M(which is the second cheapest truck out there). The RR depreciate like crazy while the Cayenne turbo is too $. Thinking about it the the X5M is sounds like a steal compared to the other two that I just mentionned. If I had to buy an X5 I would go for the diesel version.
