I'd been going to Diablo Auto Specialists the past couple years and had really good experiences…read morewhen Jon was running things. We had 4 cars we took there and always had confidence in the work. Jon's gone and I'm stunned with the change in service now. They don't offer an online list out of items inspected including pictures showing what they've found, and recommendations for work needing to be done. They don't text you with an estimate. They don't call if you need something replaced; you find out only after you show up. The customer service is gone. But it's worse than that. But what really shocked me up was opening up the hood of my car to add some washer fluid only to notice the air filter housing was still unclipped, which seemed negligent. But opening the housing I discovered the air filter was missing entirely! They serviced my car 5000 miles ago and my car didn't have an air filter put in. I was just planning on taking it in for service but it won't be with them now. I'm livid! I'm done with Diablo Auto Specialists, or Autoworx or whatever name change is going on there. I would never go back and would highly discourage anyone else from going there.

Love Diablo Auto Specialists. They take great care of us and our cars. We have older cars that are…read morein great condition because of them. John always explains everything and is really honest about what absolutely has to be done and what can wait. Also really appreciate that we don't have to hound them about when the cars will be ready. They always keep us in the loop on what's going on. Prices are reasonable and we know that they get it done every time so we save money not chasing a problem. Very very highly recommend Diablo Auto Specialists!

About a year ago I got quoted $1,400 by Midas to get my axel boots replaced on my Toyota yaris. I called him in desperation-- my parents had brought their cars to him before but I had never brought mine in, but I had heard great things. I left a message and a couple days later he called back and said I could bring in my car early in the morning so he could take a look, no appointment needed despite his crazy busy schedule. He let me know that the issue was not nearly as bad as I had been told and that he could do the job for half of what Midas had quoted me. This was my first experience with him and he has consistently shown how much he truly cares about doing right by people and taking care of their cars honestly and to the best of his ability. I feel like I could trust him with my life. When he retires eventually I will have to go into mourning. If you are not sure whether the wait for an appointment is worth it, ask yourself if you can afford to pay double whatever he will charge you to another mechanic who will not be nearly as thorough as he will be. Recently, when he had to refer me to another shop because I needed a service he doesn't provide, he asked me to still follow up and let him know how it went after the work was done, just out of the pure kindness of his heart. He is a one in a hundred million kind of mechanic.

I have a 2019 Lexus ES300, and when I took it to the dealership, they gave me a huge list of…read morerecommended services with a very expensive estimate. I was honestly stressed out and wasn't sure what to do. A friend told me about this shop, so I decided to get a second opinion. That was the best decision I could have made. The staff took their time to go through everything with me and explained each service in a way that actually made sense. They were honest, professional, and never tried to sell me anything I didn't need. They completed the repairs using OEM-quality parts and charged much less than the dealership. The difference in price was unbelievable, and the quality of work was excellent. My Lexus is running great, and I feel much more confident knowing the work was done right. It's rare to find a shop that is both knowledgeable and trustworthy. If you're looking for honest service, fair pricing, and people who genuinely care about their customers, I highly recommend this place.
