I would vote for A&A, but not sure if they do routine maint?
I am in Camarillo and use this shop - J&K Automotive
http://www.jkautomotive.com/. Very talented young guy who grew up around engines. Rebuilds them, Drag Races his 1,000=HP blown 69 Camaro and a front engine rail, and works an a drag race team as a mechanic. I trust him with all my cars! Just did rotors on my 17 Camaro, and he does my track prep.
Be sure that Matt (owner's son) is the guy, as I am vouching for him.
