I've had luck with Silver Star Auto on Old Almaden and San Jose Street, just off the Almaden Expressway. The owner, Steve has been very fair with me and does a very clean job! He used to work for Smythe Mercedes as a tech then went out on his own.He's from Germany so it took a while understanding him because of his accent! I recommend him, and tell him George Kern with the 1989 300E sent you. Look his phone # in the book. I have but can't find it right now.
