I appreciated your care during the Covid 19 crisis. Your service is spectacular, but the extra care you took this time blew me away. Totally contact free. Masks and gloves were used Payment over the phone. All were so important to me.

I’ve been taking my cars there for a few years to get Smog Certificates. Excellent customer service. Everyone is courteous and professional. I made an appointment for today. They took my car in right away and it was done in 30 minutes.

The entire staff of Certified Automotive Specialists was amazing! They are courteous, prompt, careful and thorough. What more can you ask for when they are fixing your vehicle? The location is spotless and welcoming and I highly recommend this location.

The staff was very helpful and friendly. They communicated anytime there was something new that they would have to do. They also gave me an extremely fair price. The company, from what I have experienced, is very honest. Highly recommend.
Landon Dial
Staff was very courteous and knowledgable. They took the time to explain exactly what was wrong with my car. They also went above and beyond, providing me a list of items that would be most beneficial to repair. Great price and service! Will be back again.
Jacob Jensen
I first brought my car to Certified when another well-respected auto repair shop could not fix my problem after replacing over $1,000 in parts I apparently did not need. Certified quickly diagnosed the problem and made the repair for less than $200. I have been coming back for years and am very pleased.
Elvin Nixon
In my search for a quality and honest mechanic for my VW Passat I came across Certified through the internet. They lived up to their great Five Star reputation. Outstanding and friendly service. I have found my car repair shop for the entire family. The staff is amazing. I highly recommend Certified Automotive.
Hugo Jimenez
Always very helpful and honest. Convenient ride transportation in a cool car if you need it. Couldn't ask for a better group of people. Our whole family gets all of our cars serviced here and we have for awhile now. Always super professional and friendly!
