This review is way overdue. I know I took too long to leave it but better late than never. I know a…read morelot of people have a hard time finding a trust worthy auto service shop, I was one of them looking all over Concord. I came across this shop because my friend knows the owner. First time I came here was for a basic oil change, since then it has been about 3 years now trusting these guys. Ken is the owner, him and his team are quick to respond and have a great system when getting your vehicle worked on. They will send you a link with a break down of the work and cost before proceeding you will have to sign it. I had a couple of my trucks with an oil leak, their mechanic Jimmy is the man. He has fixed a couple of my trucks and I just couldn't be happier. If you are looking for a good auto service place this is the place you can trust. Give them a try and I promise you won't be disappointed. Thanks again Ken and your team for always taking care of me.

I didn't know who to take it to, and I don't know much if at all about cars. I had it towed while out of town directly to Jon, and he had it fixed and ready to go in no time. Jon is the best!!! Thx Jon and Diablo Auto Specialists for getting my vehicle back running smooth again and for being unicorns in the industry; having integrity, being ethical and not cheating people out of their money! God bless all of you!

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.

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.
