My first call was to Walnut Creek Smog and they told me they needed to calibrate the machine and to come in an hour. I showed up and was greeted and they quickly got to work.

I was honestly stressed out and wasn't sure what to do. A friend told me about this shop, so I decided to get a second opinion. That was the best decision I could have made. The staff took their time to go through everything with me and explained each service in a way that actually made sense. They were honest, professional, and never tried to sell me anything I didn't need. They completed the repairs using OEM-quality parts and charged much less than the dealership. The difference in price was unbelievable, and the quality of work was excellent. My Lexus is running great, and I feel much more confident knowing the work was done right. It's rare to find a shop that is both knowledgeable and trustworthy. If you're looking for honest service, fair pricing, and people who genuinely care about their customers, I highly recommend this place.

FINALLY!! A smog place I (and you) can trust…read more I came here as a last ditch effort in attempting to smog my wifes 2015 Chevy Malibu. We were getting some bad codes that prevented it from being smogged and I went to another smog place in Concord. I was sold approx $800 in repairs and THEN told that I should call CarFax get a quote and take it and get rid of the car! This 2015 Malibu is hardley drive as I work from home 100K milles. After hitting another auto repair place it was told to me... Im betting this would pass go to BAYSIDE SMOG... I did and Im glad I did. Retold my story to Naqib and he smiled and stayed neutral on it while seeing the disbelief in his eyes on my being told the car would cost more to repair and smog than to just "sell it as is" It took them 15 minutes maybe to smog the car with no issues... no weird side gimmicks or tricks, the car just passed as it was. Bayside has a lifelong customer and Ill steer everyone needing a smog to this guy. Solid service!

They were quick and efficient leaving me with atleast 35mins to spare on my lunch break. Their pricing is fair or better than other.

I know a…read morelot of people have a hard time finding a trust worthy auto service shop, I was one of them looking all over Concord. I came across this shop because my friend knows the owner. First time I came here was for a basic oil change, since then it has been about 3 years now trusting these guys. Ken is the owner, him and his team are quick to respond and have a great system when getting your vehicle worked on. They will send you a link with a break down of the work and cost before proceeding you will have to sign it. I had a couple of my trucks with an oil leak, their mechanic Jimmy is the man. He has fixed a couple of my trucks and I just couldn't be happier. If you are looking for a good auto service place this is the place you can trust. Give them a try and I promise you won't be disappointed. Thanks again Ken and your team for always taking care of me.
