To start off.. I read every review carefully because I'm that kind of person. I am utterly and completely skeptical about mechanics, being a single female who doesn't know enough about cars, I have heard and experienced enough horror stories to find nearly all mechanics suspect. That being said. 1. I dropped in without an appointment after a simple phone call to get a check engine light diagnosed. Their diagnosis was accurate and correct, offering a simple, low cost solution (fixing a sensor) over replacing the full thermostat as Royal Motors and two other mechanics had tried doing (thought he unit was fine). 2. They (rightfully) diagnosed my battery as being near dead, saving me from being stranded road side.3. Fixed a very nagging and pain-in-the-ass mildew smell, that was caused by build up of water in the drainage piping that leads from my sunroof to the door jam, by using a razor blade there by saving my health (I had developed asthma from allergy to mildew and mold!!!) Pretty much --these guys have been awesome so far. Granted this shop isn't as cheap as I would like (ok, I'm spoiled .. a good friend was a VW Mechanic before moving to SF), but they are honest, explain things clearly, are conversational and make you feel at home (including offering me a ride home when I unexpectedly had to leave my car). 5 stars for accuracy in diagnosing a problem5 stars in saving me money5 stars in professionalism, customer service, and personal touch5 stars for all around awesome service. I have another appointment next month and will update my review then. So far, so good.
