Why Choose Us:

Not only are we a family run institution that has been serving our community for over 15 years, but we realize that at times a smog inspection can become a stressful situation for anyone. Therefore our goal is to make this as easy and stress free as possible for all our customers. It may help to know we are exclusively a Star Test Only Smog Check Station. The Star means we've been recognized by the state as a station that performs their inspections accurately. The Test Only means we do not perform any adjustments or repairs if a vehicle were to unfortunately fail, which means we have absolutely no reason to fail a vehicle because, not only does the customer not leave happy, but we gain no profit from it. However once a vehicle passes a smog inspection a certificate is automatically issued to the DMV, the customer is given a hard copy for their own records, and you're done. Simple as that! Our goal is for every customer to leave happy and content, and to keep wanting to come back.


The only thing as important as a job well done is a job well done quickly. Ruiz Smog Test Only prides itself on being efficient. With most smog inspections taking no more than 15 minutes, we try to get every customer in and out, and back to their daily life.


As the saying goes practice makes perfect. With our over 15 years of experience you can bet on us to get the job done exactly to your needs. We stay up to date with all Bureau of Automotive Repair rigorous requirements and consumer programs available to better serve you.


Our clients are the only reason we are in business, and word of mouth is the best sort of publicity we can have. We never forget this fact and do our very best for them every time.

Ruiz Smog Test Only: Business Done Right

The business world is extremely fast paced because, as the saying goes, time is money. Unfortunately, because of this mindset we have lost some of the most important aspects of human interaction. That is why Ruiz Smog Test Only makes the time for our clients. We want our clients to know that when you deal with Ruiz Smog Test Only it is not business as usual. We take the time necessary not only to get the job done, but also to get to know our clients and provide them with an atmosphere that encourages them to come back. We encourage our clients to speak freely with us, ask us as many questions as they can think of, voice their concerns, and inform us on how we can better serve; that way we can make sure that their expectations are met and exceeded.
