    Theo is a great guy with integrity. Always had a great experience! I highly recommend Smog Dynamics to anyone looking for a fast, affordable smog from an honest locally owned business.

    ! The shop closes at 5 pm, but Theo was very accommodating (as I didn't get to his shop until after 4:30)

    Amazing service! My…read moreson was driving to So. Cal to spend a week with his brother before the brother got married. Just a carefree week of bachelor brothers hanging out. He was supposed to drive there on Saturday and get to So. Cal before dark. However, he left after dark. He passed Los Banos (Route 33 exit) close to midnight and his engine started running really rough and it was losing power. He limped to the next exit, at less than 25 mph, turn around, and come back to Los Banos. We picked him up around 1:30 and got back home at 3AM. At 8AM (Easter morning), we started calling mechanics in Los Banos. Of course, we used Yelp and sorted by ratings. We went down the list and left messages for everyone. We just prayed that someone would be willing to work on a holiday. Jesse was the only one who answered the phone. We explained our predicament. He agreed to help if we could get there by 10. He had a family picnic planned. My son's car was parked about 2 miles from Jesse's shop. We were able to get it running and over to the shop before 10AM. Jesse found the problem, was able to obtain the necessary parts, and had the car fixed in about 3 hours. He charged a very reasonable amount. My son made it to So. Cal before dark (a day late), and Jesse still got to spend the rest of the day with his family. If anyone I know ever needs a good mechanic in the Los Banos area, I would highly recommend Jesse and Advanced Service & Repair. Thank you, Jesse. God bless you.

He has shown more generosity and kindness than I could have asked for. I highly recommend him to anyone looking for someone to work on their car! He is genuinely a great guy. He also resolved the car issue in a timely manner.

    I was passing through the Bay Area when I had my vehicle had a headlight issue. I stopped at a…read morelocal gas station and inquired about a reliable mechanic in the area. They recommended Lou's Auto Repair. Let me tell you I'm beyond grateful for their recommendation. I found Lou to be every bit the man they described him to be. Honesty, reliable & trustworthy!! Lou took a look at the headlight issue, quoted me a price, and went to work. I found his work to be above and beyond what was expected. He even took care of a little loose fender issue for me without even being asked to do so. It's the little attention to details sometimes that tips the scale from an average experience turn into a fantastic one!! I too now will always recommend Lou's in Burlingame for all your automotive needs!! Thanks Lou!!

I previously went to another auto repair who listed several issues (engine oil, brake belt, leaking water coolant, replace filters, tires, etc). I definitely needed serious repairs done. The previous shop quoted me $3k including labor. I asked around and was recommended Lou's. I called 730am and he called me back 15 mins later and welcomed me to bring the car by for a free inspection. He said the previous shop was correct in their assessment. I did need all those repairs but a couple could wait until my next oil change or in 5000 miles. He also said I could go to Costco to get my tires done (a place that referred business elsewhere def means he's looking out for customers!!). He quoted me $1696 including labor!!! I was shocked and grateful for his honest quote. I was able to leave the car and pick it up at the end of the day. They also test drove it on the streets and freeway to make sure everything was solid. I cannot rave enough about Lou's. I trust him and his crew 1000%. He made a life customer.

    Where do I begin? The Auto Shop is #1 in my book In Modesto!! Thank you, Thank you, Thank you!…read moreBruce and Larry and the mechanics at the Auto Shop as they are simply amazing. They've diagnosed my two cars and repaired it properly each time at a very affordable rate. They treat you like you're family and that really says something in the auto repair business today. The real test for me though was after a repair for my Toyota Avalon. A part that they replaced began to smoke a week after installation. I called up and told them what had happened, and they towed me from 1800 McHenry to their shop, went to Sacramento to get the new part I needed and had me back on the road in 4 hours the same day!! And when a problem arises, you can tell the good from the bad Mechanics just by the way they "handle it!" You know what Best part was? They didn't charge me for labor, parts or anything. They just took care of it. Who does that anymore?Well, they just honor their customers. Gosh if only all businesses could do this like they d? What a world it could be. Thank you so very much for keeping me driving Bruce and the Auto Shop Team. You guys rock:-)

They were supposed to change it out for an aluminum one, they didn't. I had to take back in because they didn't install it right it leak oil all over the place. I had have the engine power washed to get all of oil out of the engine valley. Now I had to take it to get the manifold replaced because they stripped out the threads when they replaced the oil heater.

When I was trying to pre arrange to bring in my car to get checked on he wanted to have it there on his time and not mine. Once I agreed to his time and date he acted like he gave into what I needed he asked why I showed up that day and claimed he agreed to Monday. But I'm a very meticulous person I had Friday on my calendar he even made a comment for me to uber to work bc I said It would be an issue to bring on a work day and a non issue on my free day. When he finally got the part for my car he waited until I showed up to tell me the part didn't work out. So he left it in when I asked why he didn't simply communicate with me and put my old part back in he said it was too much or double the work. Then later proceeds to call me to say he needs the car back to take out the part and put my old part back because he needed to return the part. Very strange bc he could've saved both of us some time just doing it then and there. When I asked for my money back he said he was going to deduct 100$ for the "work" but I don't think it's just taking in consideration that my car was not fixed. He ordered another part and claimed it arrived broken so I'll just take it to Honda and pay whatever their fee is to get it done correctly. He also refused to give me any invoices / itemized receipt for the parts / work being done. Saying it would've been more to write it up in the shop meaning I don't know if I'm being charged accordingly or overcharged.
