Castro Valley 76 in
Castro Valley (CA)

Jay always takes such great care of my car. His attention to detail and his knowledge of cars is incredible and I trust him to always have my best interest in mind.

Customer service was excellent! My service was executed exactly how it was sold to me in the time frame that was given.

Great service where I trust that what gets done is done as promised.

Needed to have my serpentine belt replaced. So, I gave Jag a call, having used his business years ago. He scheduled me the very same day and had the work done in just over an hour and for a very fair price. How can you beat that? Hence the 5-star review. I was so impressed with this, he's going to do my front brakes too - also reasonably priced. Edit - 2/4/26: had brakes done today. In/out in less than 2 hours and everything working well. Jack will be the person I call for any/all service I need from now on......5 stars again.

The service was very professional.... I like how they keep me informed as to what they were doing ????

Loved the service. You guys were fast, courteous and communicative. I have to say that I misplaced my earbuds and the last location they were active was at the shop. I came back a little after hours and one of your mechanics was still there. He was very kind and helped me look in the lobby. In the end I found them but I can’t get over the professionalism and customer service.

Excellent Service, Jay’s team did a great job diagnosing the problem and a quality fix. I definitely will return for continued service

Thank you so much you did an awesome job my care is running so much better!

Ive been going to Phillip 76 (Jack & Jay owners) since 2001, they are the best they always take care of my vehicles, thank you Jack & Jay.

Professional courteous service with strong customer focus. Repairs performed on time and within estimated costs.

Had an oil change and whispers put on. They were nice people. I’m going to get a tuneup soon with them.

I always have the best experience with Jack and Jay. I’m always confident in what they tell me and as a woman that’s very important to me. I highly recommend them, you won’t be disappointed.

I have trusted these guys with my cars for the past 10 years. They do good work, it is always done correctly, and is reasonably priced.

Great experience taking my F150 in for new brakes. Decided to take my truck there to support local business and was not disappointed. Customer service was outstanding. I appreciated that they explained all my options and provided a fair quotes. In Castro Valley, I highly recommend this business, you can't go wrong!

Jack and Jay and the team at CV Union 76 are incredible. They repaired my ‘06 Lexus after it was hit in an accident. They also did my tune up, cleaned up my lights, fixed my electronic key and got me a 2nd one, replaced my axels at half the cost of a quote I got from someone else, and much more. I basically have a new car now. They are knowledgeable, always provide great customer service and they are very reasonably priced and the communication is top notch. They worked with my insurance company who was not the easiest to work with. They are PROs!! I will always bring my vehicles to them. I trust them.

You won't regret taking your car here. They provide excellent, friendly service and very affordable prices. I've been taking my car there for years. Won't go anywhere else!

Jay was awesome. Great service. Got smog check, oil change and tire rotation done fast. Fair prices. Family owned shop for 50+ years.

Took my car in at 7:30 AM to repair a tire with a nail in it. They had me in and out in less than 30 minutes. Reasonable prices. Excellent service. Everyone was very friendly and professional. Thank you for taking a stressful situation and turning my day around!

My Brother Jay always takes care of me and is very confident of his work. If there is ever any issue he never charges me extra and he makes sure that I’m satisfied. I’m not going anywhere else anymore. I enjoy the love that I get when I show up, can’t find better business and the love is free. I advise that this is place of automotive service that we all should go to. If you can find better, more power to you. Good luck..

Jack, the owner, was friendly and sensitive to my needs. He went out of his way to put me at ease and made sure everything was done in a timely and professional manner. I highly recommend his automotive service shop.

The car was checked with repairs I needed(starter,timing belt,plugs etc.)the price for parts not bad,labor for work,well that’s what would be paid anywhere you go.The bottom line is Jay didn’t over price parts and labor,you want an honest and trustworthy place to take your car(smog etc)Castro Valley Union 76 is the Mechanics you can trust
