I highly, highly recommend them. I'll definitely be referring anybody and everybody I know here. I seriously can't say enough good things about this place. Five stars all the way

Based on small-talk with the mechanics, some of them work at multiple locations and they seem more like contractors? To be honest, I've had two slightly poor experiences, once with an employee who blew me off and another time when the work wasn't quite done properly. I'd dock half a star for that. However, each time the manager or owner, who I believe is named Glenn, was able to set me right. (Older gentleman with a beard). I feel like the price I pay for services is fair, and each time I come here the work has been done quickly and efficiently. Overall 4.5/5

They told me they inspect the entire car and that it would be 195$ for an inspection. I told them what the problem was, that there was a noise and vibration while driving over 30 mph and the guy explained it could be a number of things and that they would check the entirecar for problems. They called and told me that there was nothing wrong with the car but I needed new tires, and that the noise was coming from the tires. I decided I would go with another shop for cheaper tires. When I went to pick my car up I noticed it was in the exact same spot and position as when I dropped it off, it seemed strange but didn't think much of it. After getting new tires the noise was still there and now louder than before. I took it to another shop and within seconds of looking at it they told me both my struts are bad and a number of other things. I explained that I just had it inspected at My Mechanic, and the guy proceeded to tell me there was no possible way they looked at it and didn't notice anything. So I called My Mechanic back to ask them about it. I asked exactly what they do for an inspection and he said they inspect the entire car everytime, when I tried to explain that it did not seem as though they inspected it do to my struts being completely broken and that he did not inform me of that he hung up on me and blocked my number. This shop is connected to Mobile One in Rhonert Park the owners name is Glenn Meyer and I will absolutely never do any of his businesses, either shop ever again. I highly suggest you don't waste your time money and sanity either! Below is a photo of the struts that were ignored .

He took my car in and when I returned, he said he can't smog any cars 2000 or newer because system in Sacramento was down. He forgot to give back my renewal paperwork before I left. so when I came back minutes later, he was smogging another car on a different machine that was newer than 2000 and said it's working again. His price was $85 without coupon. Company's website offered $10 off for any customer lowering the price to $75. I had a coupon for $65 for smog, so clearly he ditched my job, made some bs excuse, and went to the higher paying job. Never going back to this doofus.

The staff are friendly and usually always keep me updated on my car's status. I have been going here for 4 years now. With that said, they are not always the quickest.
