They explained everything clearly, provided great customer service, and had me in and out in no time.

I'll definitely be coming back and recommending them to my family and friends. Thank you for the outstanding service!

I only found out by doing one of those Yelp quote requests (from various competitors, did it sheerly by accident trying to make an appointment at a prior place I went to). It's a no frills place. No appointments. Walk-ins only. We were lucky in that the person before us was just finishing up when we arrived so we didn't have to wait too long. The waiting area is a few fold-up chairs in a square concrete area that is quite sloped.

There were 2 cars in front of us when we went, and they still got us out of there quicker than most smog joints. Waiting room is clean, if stark. There's a bathroom if you need it. But man, the music was SO LOUD. Like, the receptionist was yelling over the music, "OKAY, SIGN HERE!" and when she grabbed the remote, I presumed it was to finally turn the music down. Nope. She just changed it from '00s pop to contemporary country. There's an option for a tip at checkout, which always makes things nice and awkward, regardless of tip level.

Said I needed to take it to a mechanic and have it looked at and then come try again within 30 days for $10. I asked why, what he thought was wrong and he said he didn't want to lead me wrong because he is not a mechanic. To go see a mechanic. That was a bunch of bull**** what he didn't know was that my dad is a mechanic and has his own smog guy in his shop. I could have went to him in San Jose but didn't, instead paid for convenience. So did what smog dude at Chevron told me to do and took my car to my mechanic and he looked at it and their was NOTHING wrong, then his smog mechanic guy did a smog check the very next day and it passed. He said straight out that they cheated me and most likely if I did bring my vehicle back, he most likely would still failed me. So just be careful, I paid $75 for fail, gas to SJ and back and $45 to get it smog check again in San Jose. If my dad wasn't a mechanic I would have paid for more out the pocket.
