Southbay Autohaus, Chula Vista, CA
Found them 12 years ago when I moved to CV; polled owners in a shopping center who were driving older, "well loved MBZs", stopped polling at 10 of 10 for Rick and Gary at Southbay. Honest, straight shooters who have kept my 560SL, my daughte'rs 320CLK and wife's ML500 on the road and running super. All MBZ trained mechanics, no extra work without discussion; great at telling you what can be deferred and what needs to be done now. I've found pricing to be reasonable and every person I've recommended them to has come back with extremely positive inputs. They are locals, know all the local shops and can steer you to other experts for work they don't perform - upholstery, conv tops, alignments, etc.
