Ive known Sean at Unibuilt for years. Hes worked on a number of my cars as well as those of friends and family.Hes done work on both imports and domestics: everything from basic maintenance to engine swaps and rebuilds, to turbo and nitrous applications and all the supporting upgrades. His automotive knowledge is impressive and hes great at diagnosing random problems and elusive gremlins hiding in the engine bay.He is really busy and it can be hard to get scheduled sometimes, but knowing a good mechanic in high demand is probably a good thing!Id recommend Sean in a heartbeat to anyone needing a good auto tech.

I have known sean for over 25 yearsBest mechanic in the inland empireHe is honest with great knowledge of carsI always go to him for my car needs

Been coming here for years, Sean has always been straight to the point for any repair or performance upgrade that I wanted. He really cares about his customers and is EXTREMELY knowledgeable and helpful during his business hours or even after. Sean can help you have a reliable car or even a reliable race car. Whatever you want or need done he will make sure that it is completed to the best of his ability. This is the only place I trust to work on my car. He does not try to scam people like other shops do. If your looking for any kind of mechanic work, performance parts, rebuilds or anything else this is the place to go. This automotive repair/performance shop cares about their customers and will provide work that is top notch!

Our truck passed everything on smog but failed ignition timing. Was a 3 but needed to be 10.Called this mechanic randomly off google to see about fixing the timing.I was told by another mechanic (before calling this one) that we should of passed the smog.We meet with Sean and he also said that truck should have passed. He set timing to 10 right in front of us and said we shouldnt have to pay the re-test fee and for us to say something. That if he fails us again he is failing purposely that he would have us use his smog guy.So happy I found this mechanic he is one of the very few honest mechanics around.We will definitely go back to him for any car repairs needed.Thank you Sean for being honest there arent many out there. Im positive if we went somewhere else they would have ripped us off especially with this covid-19 happening.

Sean was very helpful and very knowledgeable about my car. He took the time to show me and go through the whole car and to give me an idea of what needs to be fixed eventually since I just got a used RSX type S. He was not pushy at all with any of the work he recommended just wanted to provide the extra step to let his customer know where the car stands. I plan on doing a k24 swap there in the near future. He also came in to the shop on Sunday just to work on my car.

Great mechanic fix the problem fast and affordable

Sean is reliable and provides unparalleled work I was guaranteed good and fast service and I received great and very fast service I highly recommend anyone to Sean good work from an incredible and reliable mechanic I’ll definitely be taking all my cars here thank you for fixing my car and it’s many issues.

Came here for some g35 quotes on turbo and the owner just has some of that bad gangster attitude.He did answer my questions but I felt like he was being very pushy and he kept using cuss words all the time. I didnt like how he bad mouthed a few other shops to make himself look good. Business here looks slow, so I feel like I now know why his business his slow.

Sean takes care of All my maintenance needs!

Highly knowledgeable and extremely experienced in automotive repair and aftermarket installations. Good work isnt cheap and cheap work isnt good.
