my check engine light went on and i took my car in to sf autoworks. they read the code and told me what it was for no charge (other places charge at least $50 for this) and told me to come back if it went back on. it did, so i made an appointment for 2 days later and they read the code again and figured out what the problem was-- it had to do with my stereo, so they referred me to a reliable audio place and didn't charge me anything, again! amazing. they seem very conscious + concerned about being a good auto business....they had an article on their front desk about how to find reliable auto mechanics and had clippings from newspapers saying that they were among the best in the bay area. highly reccomend.
