I agree with some of the other folks....the pics on this thread look nice....but hop on over to the official site and see this thing in 360 degrees and the back of it and you could mistake it for a hyundai....not good.
Also in AUD prices the x5m is 100'g cheaper than the top of the line cayenne turbo s and the X comes with every option equipped while the Cayenne still has plenty of boxes to tick

.....my personal opinion.....bit of a rip off.
From what I have found out, the Xs have more frequent visits to the dealer than cayennes but when you need to take you cayenne in better get your wallet ready.
