What is the Difference between Emissions Testing and a Smog Check?

OUR REVIEWS
Kimberly Hengsteler, 05/10/2023Too many good things to say about Paul (owner) that I am going to just highlight a few. However, I am happy to answer any questions or add more if requested. Paul is knowledgeable, honest, and understanding! He loves his job and it shows. I would recommend Superior Auto Clinic to any and ALL, especially if you are tired of being lied to, misled, disappointed, frustrated, or are a female! He treats all his customers like they are special and truly just wants to help you, me, and everybody. Thanks Paul (and Rudy) for all you do to keep our cars running smooth!
