The guys at this shop are awesome. Friendly and efficient. I feel like they are not charging any more than necessary to get the job done. I've had to visit them twice in the last few months. Once for a cracked exhaust manifold and the other for battery terminal issues. They got the jobs done as fast as possible and even picked me up at my house because Of logistics transportation issues with a toddler and car seat. They go above and beyond to help their customers. read more

First I wanted to start with thanks to John and Jarvin for doing such an excellent repair job on 2009 Toyota Corolla I've already seen marked improvement in power and performance. Future more, i just purchased Corolla few days ago for my kid therefore i was doing the tuneup on my own prior smog while i was extracting Spark Plugs one of the plugs broke partial of got stuck in cylinder; a Nightmare! so i called Jarvin at "One Start Auto" Jarvin advised me not to panic call my insurance company and have it towed to shop first thing in the morning. Moreover, usually in this situation Mechanic has to take the Head Cylinder off in order to repair this issue, luckily John the Master Mechanic also the shop owner had a lot a experience time in service and stayed over late to repair the issue without taking the Head Cylinder off. Finally, at late evening around 7pm John successfully removed broken Spark Plug from Cylinder #4. Next day Jarvin inspected car diligently made sure it is safe for my teenage new driver kid. service I received from Jarvin and John from (One Start Auto) far surpassed my expectations! Your Conduct and Honesty reflects your professionalism. Thank You! -Happy Customer read more

Took my 2005 SUV there today and had brakes done and a good look over. Thanks to John and his partner, they found a big nail in the tire and found metal sticking out of the tire . I will definitely be going back! read more

I was recommended by my mom who took her car to John and Garvin. She passed away in 2014 but we ( my whole family) have been going to John since. He's a wonderful person and a great mechanic. He will check it out first to see what's wrong and if he's able to repair it. He won't overcharge you, he's fair, he does quality work and I always call him whenever we need advice. Great place to take your car. You will not be disappointed!!!! read more

I didn't even pay for any service but I still had a 5 star experience here. We were wondering if our battery was going out so we swung by to have it tested. He checked the battery and ruled out other problems. The battery needed to be changed, but instead of charging us for labor and installation he directed us to where we could get the best price. I support local business but the battery prices were pretty significant. I hope other businesses take note, sometimes helping someone out will make a customer want to return in the future. Nickel and dimeing isn't a good long term plan. I recommend this place. read more

I've been taking my car to John for only 2 years, in the short time that I've taken my car on an emergency basis, he and his crew have always been very conscientious about my time. They have been efficient, thorough, HONEST, and very knowledgeable about my car issues. As I wait for my car, I've observed John and his crew treat people as if they are family and with professional respect. I RECOMMEND THIS PLACE TO ANYONE! You will not leave unsatisfied!! read more

John and Jarvin are always so nice. They do a fantastic job and never try to price gouge. I will always take any I've my cars here. Not going anywhere else!!! read more

John and his partner have always done me right. They have never tried to gouge me for unnecessary parts or labor and are more then willing to offer free advice on things you may choose to do yourself. I recently needed a new gearshift cable because car would not go into gear. John searched everywhere but it simply was not available. He improvised and managed to make a cable and got me back on the road. I highly recommend this shop! read more

I have submitted a review before, that being said, the treatment I received this week deserves a longer more detailed review. I work in the automotive industry, truth be told I work some place where I could have all my auto repairs done. That being said (and no there is nothing wrong with the shop where I work) these guys go above and beyond every time. I can't even count the times I've brought my vehicles to them. So , this week my daughter was headed to work , she leaves for work at 4am and we live in the country where there are not many street lights. Some jerk decided to leave a black futon in the middle of the road, my daughter didn't see it and ran right over it. I knew bare minimum she'd need a new radiator. I call John and he says no problem bring it on down we will take a look. Now if any of you have teenagers you know they are impatient quickest way to upset them is to take the car or phone away. The guys went out of their way to repair her radiator and condenser. They even texted me photos as the work was being done. The quality of work they do is beyond compare and they explain in layman's terms what's going on with your car. They had my daughters car looking good as New in less than 48 hours and at a reasonable price! I highly recommend them with no hesitation to anyone who asks where to get maintenance or repair work done! Great people , amazing service! read more

Great customer service! Gave me a free first oil change and tire rotation. They really care about their customers and are willing to answer any questions or concerns. read more

Great place to take your vehicle very professional great customer service highly recommend them.

My beloved Lemon Drop and I were stuck relatively far from home, and AAA towed me to this shop. I could not have gotten luckier. I think that every one of the exceptional reviews are well deserved. John is skilled and very, very fair. Although a little farther from home than I would normally establish any kind of regular service, I fully intend to keep bringing my Lemon Drop back for all maintenance and repairs. read more

Best auto repair shop in the area. I live in Merced and get my oil change and any service my vehicles may need done here since I've been a customer for over 5 years. John is super knowledgeable and knows how to tell me what I need in a way that is understandable for me since I have limited vehicle repair knowledge. All you can ask for in a mechanic is an honest answer to what you need and John does just that. Him and Jarvin know what they are doing and I highly recommend this shop to anyone that is looking for good, honest, trustworthy and reasonable mechanics. read more

John and Jarvin, thank you for your awesome customer service and your expertise. Great work ethic goes a long way today. It's no wonder you guys are so busy! read more

John and Jarvin are both very professional. I have taken every car I own to John for the last 13 years and he has always been fair and honest with me. He will never try to up-sell you, always lets you know what needs to be fixed right away and what can wait. I highly recommend One Start Auto. read more

Took my money and left me with a dangerous truck that stops running. At least they know how to cash a check

John is a very knowledgable, honest mechanic. He always shows you the parts he replaces and is very fair on prices. I don't take my car to anyone else. read more
