My understanding is that ALL X5 are made in the U.S. although all the parts, assembly, technology, engineers, etc. are from Germany. In terms of Reliability, I think these are great SAVs. They will run a long time if you do the proper maintenance. Unlike many other cars, the X5 has predictable problems which are easy to fix if you are on the look out for them (i.e., CV boots, window regulators, etc)

Hope this helps
