Services
What we work on
- 01
Diagnostics
We trace a check engine light or rough idle back to its actual cause before recommending anything, using the tools and the parts on hand.
- 02
Brakes
Pads, rotors, and lines inspected and replaced, with the worn parts set aside so you can see what came off your vehicle.
- 03
Oil & fluids
Oil, coolant, transmission and brake fluid checked and changed, with any leaks or low levels flagged while we're under there.
- 04
Engine repair
From a failing fuel injector to a bigger internal issue, we diagnose the actual fault before recommending repair over replacement.
- 05
Smog & inspection
Pre-smog checks and repairs for the issues that actually cause a failure, addressed before you head to the test.
- 06
Batteries & electrical
Batteries, alternators, and wiring issues tested and traced, not just swapped until something works.
Our
standards
- 01Owner works the counter and the yard
- 02Parts tracked down when they're not in stock
- 03Diagnosis explained before any repair
- 04Worn parts shown, not just replaced
Find it, then fix it
We locate the correct part before we schedule the install, so the repair isn't held up mid-job.
Show the failed part
Whatever we replace, you see the old part and the reason it came out.
Diagnose before we quote
We run the diagnostic and explain the cause before any price is discussed.
A yard full of parts, run by people who know where they are
M&J sits on a lot of sheet metal, rusted steel, and gravel — the kind of place where the work happens in the open, not behind a clean counter. Martin and his crew spend as much time hunting down the right part as they do turning the wrench, because half the job on an older truck or car is finding what actually fits. When a check engine light won't quit or a part isn't sitting on a shelf anywhere else, this is where people bring it. We tell you what's wrong before we tell you what it costs.

“Went looking for some parts for my truck Martin (owner) and Beto helped me find the correct parts.”

Questions
My check engine light keeps coming back — where do you start?
We run a diagnostic to trace the code back to its actual source rather than swapping parts on a guess. A light can point to more than one cause, so we test before recommending a repair.
Can you find a part if it's hard to source?
Often, yes. Since we run a parts yard alongside the repair side, we can search for components that aren't sitting on a typical shop's shelf and install them once they're located.
How do I get my vehicle looked at?
Call or reach out to get on the schedule. We'll talk through what it's doing, get it in for a look, and go from there rather than quoting anything sight unseen.
