We carry many BMW X3 parts. Marketplace success for the X5 meant that the smaller X3 was needed. The X3 was the first compact luxury sport utility vehicle offered by the Bavarian firm. Its success led to the eventual launch of the even smaller X1. The current F25 BMW X3 is almost as large as the original X5. The first generation X3 was made in Austria but production has now moved to South Carolina.
