Auto repair in the United States is split between independent shops, dealership service departments and national chains. Independents handle most routine work (oil changes, brakes, tune-ups, check-engine diagnostics) at lower labor rates and often specialize in one make or in imports; dealers keep factory tools, software and warranty authority; chains sell speed and standard pricing on maintenance items. Most shops charge a diagnostic fee, credited toward the repair if you go ahead, and quote parts and labor separately. Certification matters: look for ASE-certified technicians and, in many states, a state repair license posted at the counter. Written estimates are required by law in most states before work begins, and you are entitled to your old parts if you ask.

The business lists hours on 5 days of the week. On most of those days it is open 8 am–5 pm. Note that it does not open on Saturday, Sunday. As with most places, expect changes around holidays; the phone number below is the fastest way to confirm. The listed phone number is (210) 590-1540. Many businesses also reply to text messages on the same number if it is a cell phone.

Matt & his pops are extremely knowledgeable & their reputation proceeds itself. Im very grateful to come across fellow automotive techs that do not gate keep their knowledge, any question I had whether if were dumb or not Matt would school me with tons of advice. I truly apreciate him inspecting the heads I brought for my 4.3 & letting me know right off bat that they were not salvagable & gave me numerous options to go about getting the right set. Got some junkyard heads they made look brand stankin new & cleaned up my aluminum intake all for a super fair price i was shocked to be honest. Do not hesitate to do business!!!

Pete and Matt are fantastic to work with—professional, knowledgeable, and genuinely committed to delivering top-notch results. The quality of their work speaks for itself. My engine has been solid and completely reliable, and they made sure to source only high-quality parts for my Big Block Chevrolet build. I wouldn’t hesitate to come back for any future engine needs. Five stars honestly don’t do them justice.

Matt and his team did an amazing job on the engine from my 99 Miata. They did a ton of work on the engine including machining the block and head, balancing the rotating assembly, installing new valve springs, and a ton of other little stuff all at a fair price. Matt gave me a ton of advice when picking out parts for my build and when I got everything back it was very straightforward assembling the engine. I highly recommend, just be mindful he's super busy so be patient if he doesn't answer the phone right away

I had the cylinder heads on my 5.3L LS completely redone, and Matt and his team absolutely knocked it out of the park. This was my first time rebuilding the top end of a motor, and they made the process so much easier. The heads came back better than new, and Matt went above and beyond answering all my questions along the way. The truck runs smoother and stronger than ever. Can’t recommend them enough—thanks again, Matt!

Very honest shop. Dropped off my block with pistons to get fitted with sleeves. Let them take their measurements and had them tell me they couldn’t source sleeves for my block (jet ski block that will be getting 26psi at 9,500+ rpm for prolonged pulls). So I am definitely a different application, but I really value and appreciate them doing due diligence and being honest about it. Would definitely recommend this shop and trust them to friends and family.
