Bosch Automotive Tradition=Bosch's Classic Center. I subscribe to their newsletter:
www.automotive-tradition.deConsidering that no Mercedes of our vintage left the factory without Bosch ignition and electrical systems, relays, fuel injection, fuel pumps, etc., in other words, the fuel didn't move, and the fuel didn't burn without Bosch, this is a good newsletter to get. I enjoy mine! Somewhere on the website link above is the place to subscribe.
