Called 415-345-9177, number listed for Downtown Smog Test Only. I was referred to 415-861-8388, apparently a new location for the people who used to be at 941 Geary. I called and the response made me feel very comfortable so I went there to what is the "Potrero Test Only Smog", located at 17th and Potrero in the 76 Station. When I arrived the pleasant man come up, knew who I was (he had asked what car I needed tested to give me a price), invited me to a seat and proceeded with super efficiency. The whole process took less than 30 minutes, cost $44.95 including the certificate fee, and I was treated graciously throughout. Highly recommended.
