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!

Mike fixed the suspension on my 2005 Toyota Corolla. This was a serious issue with control arm…read morebushings where the wheel can come off. Mike does not charge for diagnostics. I spent $200 just on diagnostics at a very prominent Toyota mechanic in Concord before coming here. Besides diagnostics, his repair price for control arms and bushings is about $200 less than the mechanic I went to in Concord. But more than just prices, Mike really cares about helping you and fixing your problem. I told him this vague issue of hearing a metal scraping noise coming from my front wheel area. Mike got in my car and went on a drive with me just so he could personally hear it and understand. The problem did not show up on our drive, so the next day he drove it himself and heard the issue and diagnosed the problem. The other mechanic in Concord simply did not care about doing any of that. It's not that the other mechanic was bad; the other mechanic was skilled as well. The other mechanic just did not care to the same degree. The other mechanic in Concord had already told me about the suspension issue. They did good work but I was unhappy with their lack of transparency about what they were doing. They did not provide images of what the problems were and I ended up approving repair items over the phone, which led to me approving things that were unnecessary and that I would not have paid for had I seen a work order. That was not a problem with Mike, his shop takes photos of everything for your review and uploads them into Tekmetric. Items are graded green, yellow, or red and you approve what you see as necessary after talking with Mike. You sign with your signature. So it's just everything that makes going here better. I was referred here by a friend whose car he fixed and I'm really glad I went here. Thank you Mike you're a great and really friendly guy!
