Is he looking for a new or a used one? Apparently the late vintages of the first edition of the X3 up until the 2010 model were quite reliable and nicely finished. I don't think there's anything like a 100.000 miles report for the new model out there yet.

At any rate, do get the X3, please, because even though it'S assembled in the US most parts are from germany and BMW pay their taxes here.
