    Thank you to Tommy for the quick fix on my car! When I arrived, I wasn't sure what I would be facing, how much the unknown repairs would cost, which is always scary. To my surprise I got a phone call from you the same day I dropped my car off, with Tommy telling me that my car was ready. It was a simple fix, a chip was loose that caused my car not to start. Tommy was kind enough to quickly find the issue, slip the chip back into place and get me back on the road, all without charging me since it was such a quick fix for him. I'm certain any other shop could have easily taken advantage of the situation and I would have never known the difference. Thank you Tommy and Diamond Auto Repair for your great service!

    Tammy does exceptional work for a very fair price. Wish more repair shops had the honesty that she prides herself in.

    Tommy was courteous, thorough, honest and prompt. Hidden gem along Berryessa. Will be coming back for all BMW-related issues.

    I bought a break fluid oil flush voucher on groupon for mini cooper. Before I went to the shop, I…read morecalled the merchant to schedule an appointment with my car info and how it's working. The owner didn't mention ay additional charges. When I went to the shop , the owner told me I need to pay additional $40 dollars for oil recycling which is not mentioned on the groupon website. I told him I can accept the charge and I need the receipt with the $40 additional charge to follow up with groupon about it. The owner said I am not interested in the deal anymore and asked me to leave and get a refund from groupon. I also noticed the owner increased the break fluid flush price on groupon from $160 to $240 after I left the shop today. It's a really bad experience for customers that the owner can change his mind and reject the service. Update for owner's review below "a vehicle that is directly not covered in the advertisement" , groupon adversisement doesn't mention any special vehicle price. After the owner told me to charge additional $40, I was confused and later accepted the charge while telling him to get the receipt for reference then I can follow up with groupon. After that, the owner refused to do the service. I guess the owner don't want his practice to be exposed to groupon. The owner could have listed the additional charge on the groupon website in the beginning to let customers be clear about all the cost. " TheThe individual came in with a vehicle that is directly not covered in the advertisement. We told him it would be an additional $20 and there was also $20 for hazardous waste because the Groupon does not cover exotic Europeans he's on here acting like a child and leaving negative reviews I offered to work with him but he was combative and at that point we had asked him to leave do the safety constraints of the business and our employees. We will not be taking well to being threatened or harassed"

    I had such a great experience with C & N Automotive and honestly wish I had found them sooner…read more From the moment I walked in, they were professional, friendly, and actually took the time to explain everything in a way that made sense. That alone is huge, because a lot of places make you feel rushed or like you're being talked over--but not here. They were upfront about pricing, didn't try to upsell me on anything unnecessary, and got the work done quickly without cutting corners. You can tell they've been doing this for a long time and actually care about their customers and their reputation. What stood out the most to me was how honest and straightforward they were. It's hard to find a mechanic you can trust, but this is definitely one of those places. If you need a smog check, repair, or even just an inspection, I would 100% recommend giving them a shot. I'll definitely be coming back here for anything I need moving forward.
