I don't think any carmaker makes a car designed to last 10 years anymore. The market does not demand it.

Our 2004 X3 has been devoid of major issues. There were a couple under warranty, and the wheel bearings are a result of poor quality roads in the Northeast, not the result of a defect. No leaks or rattles.

For a 2010, most of the automatic transmission issues should be ironed out. However, it isn't the best shifting automatic around town (works great at the track, I'm sure) so I strongly suggest ordering one with a manual transmission.
