I chose the x5 over the cayenne solely based on finances. Special financing rates, free maintenance and way better resale value made my decision easy.
But that's not to say the x5 didnt earn it's merits. Better powertrain throughout the board not to mention that silky 8 SPd tranny and great mpg. 23 on mine if I'm on a trip and 20 mpg all around.
