I have been working with a mechanic in the Miramar area, MR Master Mechanics... these guys are affordable, knowledgeable, and they don't mind when I source my own parts (which is important for a VX owner). They even let me know when work *other* mechanics have flagged as must-do are actually you-can-put-that-off-a-while. I found them as a happy accident through Yelp... some of the crew there came from Classic VW (which used to also be Classic Isuzu up in Escondido), so they have some Isuzu background. If you go there, tell them Kilna sent you.
