Updating: Still awesome. Best, and most honest, auto mechanics in the San Fernando Valley, quite possibly L.A. As noted, Shant will show you every single old part he replaces, will not go ahead with additional repairs unless authorized, and will recommend, but not in any way hassle you if there are things to keep an eye on. Rigorously honest. And he just cleaned up a scratch on my car as part of a normal oil change.
(As another customer noted, it may take a couple of tries to get them on the phone. It's worth it.)
