Excellent, timely service and crucial preventative maintenance! I drove 15,000 miles in this past year, traveling between San Francisco Bay Area and LA area, over 15 times, a 1,000 mile roundtrip each time, sometimes with the car fully loaded. Dorso's completed all oil changes and servicing of my car at intervals, double checking air filters, A/C, tire pressure, etc. because of the numerous drives through the "hot" valley, etc. I experienced NO problems with my car. Dorso's preventative maintenance and forward thinking really gives me the confidence to travel alone, long distances, repeatedly. I moved my elderly mom from the LA area up to the SF Bay Area, and now my mom takes her car to Dorso's!
