 I bought a used 2010 X3, drove it for three weeks and hated it. Rode like a brick on concrete wheels (ultrastiff).I've owned BMW's before and can say that the X3 is a complete mess.Returned it to dealer who gave me full value back - thanks Carmax. Having success years ago with an A4, I test drove the Q5 and bought it on the spot. A similarly equipped unit from Benz or BMW would be thousands more. BTW - A voluntary recall is in effect for the 2011 Q5 and it deals with a computer update that improves transmission shifting. (downshifting was a bit rough).Existing inventory on dealers lots should already be updated. The update on mine did the trick and the trans works perfectly
