    2014 Camaro SS convertible
    Chad H.

    This is the first time I used Stephan at his performance shop. He completely changed the suspension on my Camaro. He did a fantastic job and really went out of his way to get the job done right. I will use him again and I highly recommend Chevyboi performance.

    04 Cadillac Escalade

    Chevyboi Performance is definitely the shop to go to for all your LS/LT performance and repair needs and more. I brought my 04 Escalade in for a fresh new LQ9 with 243 heads, tbss intake/throttle body, flex fuel kit, E-fan conversion, wheel hubs, and cold air intake. A month or so later brought the Escalade back in for front end rebuild and complete lowering kit. I will be coming back for more work to be done to the Escalade in the future. He is very knowledgeable, professional, and his work is very clean. Not to mention he is quick and efficient to get your vehicle done. His work is excellent and goes beyond what I expected. He will do whatever you want to your vehicle but will also suggest what else needs attention after he thoroughly inspects your vehicle and suggest best bang for buck upgrades so you don't overspend on upgrades that won't make a difference or is not needed. I definitely recommend him to family, friends, and whoever else needs an excellent mechanic.

    Mike fixed the suspension on my 2005 Toyota Corolla. This was a serious issue with control arm…read morebushings where the wheel can come off. Mike does not charge for diagnostics. I spent $200 just on diagnostics at a very prominent Toyota mechanic in Concord before coming here. Besides diagnostics, his repair price for control arms and bushings is about $200 less than the mechanic I went to in Concord. But more than just prices, Mike really cares about helping you and fixing your problem. I told him this vague issue of hearing a metal scraping noise coming from my front wheel area. Mike got in my car and went on a drive with me just so he could personally hear it and understand. The problem did not show up on our drive, so the next day he drove it himself and heard the issue and diagnosed the problem. The other mechanic in Concord simply did not care about doing any of that. It's not that the other mechanic was bad; the other mechanic was skilled as well. The other mechanic just did not care to the same degree. The other mechanic in Concord had already told me about the suspension issue. They did good work but I was unhappy with their lack of transparency about what they were doing. They did not provide images of what the problems were and I ended up approving repair items over the phone, which led to me approving things that were unnecessary and that I would not have paid for had I seen a work order. That was not a problem with Mike, his shop takes photos of everything for your review and uploads them into Tekmetric. Items are graded green, yellow, or red and you approve what you see as necessary after talking with Mike. You sign with your signature. So it's just everything that makes going here better. I was referred here by a friend whose car he fixed and I'm really glad I went here. Thank you Mike you're a great and really friendly guy!

    The owner, Mike is a wonderful business owner. I can't remember the last time I received such…read morehonest & quality service. He cares about your budget, not about taking advantage of his customers. His communication is kind and thorough. I will be reccomending King Auto to friends, family, even strangers. Thank you for taking care of me, (Mama). Huge thanks to your staff as well. Grateful.

Finding Bush Motor Works was the best decision I could have made. Steve is incredibly knowledgeable, honest, and genuinely cares about his customers. The service was outstanding, and the entire team was professional and friendly. I'm excited to build a long-term relationship with Steve and Bush Motor Works and will be trusting them with all of my vehicles moving forward. Thank you, Steve, and thank you to your entire team for providing such exceptional service. I highly recommend Bush Motor Works to anyone looking for an honest and reliable automotive shop.

I'm extremely happy with the efficient work Steve and his team provided. I was initially concerned about getting the same repair done at the dealership because of the high pricing, but Steve quickly put those concerns to rest. He was honest, straightforward, and got me back on the road within a day. If you own a BMW, I highly recommend bringing your car to Steve. He clearly knows BMWs inside and out, offers fair pricing, and tells it like it is. Thanks again, Steve!

    I can't recommend this mechanic highly enough! It's hard to find someone who is honest,…read moreknowledgeable, and truly has your best interests in mind, but that's exactly what you'll find here. They took the time to explain everything clearly, never tried to upsell me on unnecessary repairs, and completed the work at a fair price. It's obvious they take pride in their work and genuinely care about their customers. If you're looking for a trustworthy mechanic who does quality work and stands behind it, this is the place to go. I'll definitely be returning for all of my future automotive needs and will be recommending them to my family and friends.

    I'd brought my older car to Monkey Wrenches twice. Once was due to a check engine light (which they…read moreidentified quickly and were able to address via a required new water pump.) The second time was, sadly, due to signs of a blown head gasket on a 2013 car with lots of miles, and not worth fixing. Both times, their staff has been empathetic, upfront on repair options and very responsive to calls and follow up. I'd recommend them to anyone in the Brentwood area needing a mechanic. I haven't had to do a lot of car repairs since moving to Brentwood, so I can't compare costs. It will be a while before I'm back, having recently purchased a newer (used) vehicle but I'd definitely use them again when the time comes. I especially appreciate Rina, who is at the front desk and will explain repair and pricing options in a way that you can easily understand. She's a a great asset to their business!
