To be honest im not up on the X series mate. I can only go as far as looks and the ride I had in in Prestige interiors 4.6l Carbon X5, and i loved it. As much as Id love you to go out and buy a big 4x4 BMW (X5) A 3 would be more suited to you Id say, for the use it will get anyway. What problems are there with the X3?
