As a single guy in Scottsdale, AZ, I figured drive a car that chics want to ride in or want for themselves, let me tell you the women here are impressed with a guy with and X5.
But I do think a lot of women do drive the X5, just like the Mercedes ML, Lexus RX330. The Porsche and Land Rover seem to be the ones guys drive in the luxury segment.
Only one guy friend, a 24 year old mustang driver, said it was a mini van, the rest are impressed with ride.
