I have heard from a reliable TRW employee that TRW(an American company)supply car parts to mostly all car companies. BMW is a major user of their parts, Mercedes also get parts from them. TRW also owns Lucas electrical systems. Parts are manufactured in the U.S. then shipped to the car companies. I just don't know if Volvo still make their own parts. Volvo was not in the topic of my discussion with the TRW employee.
