I have a loaded 2007 X3 and a 2008 M3.
I absolutely love the way the X3 drives and handles. I take clients out in it during the week, tow a motorcycle trailer and go skiing with it on weekends. I test drove several cars before buying it, and owned a couple of LR's before. Nothing came close to the overall feel of the X3.
Although the present engine has plenty of power, I've always thought the twin turbo would be a great match for it.
I plan on keeping this one until the new one comes out, but in the meantime feel that I've got a great car for my needs.
Those of you bashing it must have some pretty amazing standards. I've owned a lot of cars, and think that for what it was built to do, it is exceptionally good.
