5 /5 Ariel Nava: Dave at APEX Motorwerks is awesome. If you have a Mercedes and you want a skilled and highly competent mechanic, then Dave is your guy. We have a 2008 Mercedes E350 sedan with 101k miles on it. We bought it from a Mercedes dealer in Monterey, CA with 25k miles. When we moved from Santa Cruz back up to the Bay Area, we took it to a Mercedes dealer and for some reason, even the smallest issues cost $$$$. Fortunately for us, my father-in-law recommended APEX. We have complete confidence in Dave when it comes to maintaining our Mercedes. Even though APEX is out in Novato, we still make the drive from Berkeley when our car needs a service.
