Overall I felt good about my choice to use this smog certification center. I found Gordons shop on google maps and compared their price points with that of other star certified smog centers. This place was the most affordable for my 1990 Honda Accord. One thing that I did not ask in my search for a smog center was if the cost of retest was included in the case that my car did not pass the first time. If you are worried about your vehicle not passing smog, be sure to ask if thats included in their pricing. Gordon took about 5 hours with my vehicle which was expected as he explained the older cars require more tests and therefore take longer to complete the smog. The only reason I am not giving 5 stars is because he changed a part of my vehicle without my consent and charged me for it when I went to pick up my vehicle. He had changed the gas cap for me during the smog and did not inform me that he would be doing that. When he called to let me know the vehicle was ready he could have mentioned it. He did not. When I arrived to pay and pick up, he charged me $17 for the gas cap, which is a bit of a rob seeing as most caps (oil,fluids, gas, etc) are between $5-$10. All in all, it was the most affordable smog center near me and Gordon provided a good time expectation and smog certification. However, I did not appreciate the up charge of a gas cap and changing something to the vehicle that I did not consent to. Would still return again with the preface that I would like to be informed of all issues, surprises, and changes to the service rendered.

Great service! Fastest smog check I ever had! I called beforehand and he was just finishing a job. I was there for maybe 20 minutes!

Very nice guy and quick service. Ill be back for my next smog.

Gordons handled smog for myself and friends Ive recommended him to for several years. Always a good experience.
