Diagnosis before quote
The first answer is not always the right answer. We test before selling repair work.
About Michael
The mechanic is the brand.
Navy aviation support mechanic. Marine electrical background. Car audio and wiring experience. And a pattern-recognition brain that genuinely enjoys the problems other shops stopped chasing.
Background
Systems first. Parts second.
Michael started in Navy aviation support, moved through marine electrical and car audio, then into automotive repair. That background matters because modern car problems are often systems problems: mechanical, electrical, sensor, pressure, and history all interacting.
That is the story the About page should tell. Not “we are passionate.” More direct: “I understand systems, I trace faults, and I do not throw parts at a car until the diagnosis makes sense.”
“I hear something off in an engine the way some people hear an off note in a song.”

The promise customers should remember.
Save the car when it makes sense
Used parts, rebuilt components, and creative sourcing are options when they are safe and appropriate.
Tell the truth
If the car needs the expensive repair, we will say so. If it does not, we will say that too.
Why GM?
Because the same wrong calls kept showing up.
Trax, Encore, Cruze, Sonic, Equinox, Terrain and related GM vehicles kept arriving with the same stories: big quotes, unresolved codes, overheating, electrical gremlins, and parts replaced without the problem being solved.
These vehicles have specific failure patterns that are easy to misread if you don’t know where to look. A missing O-ring that mimics a head gasket. A P0420 that isn’t the catalytic converter. A PCV issue pointing the scanner in three wrong directions. Once you’ve seen these patterns enough times, you stop guessing and go straight to what it actually is.
Ready to call?
Tell us what the car is doing.
Referrals, regular mobile repairs, no-starts, and GM second opinions all start the same way: describe the symptoms, where the car is, and what anyone else already told you. We'll give you a straight answer before anyone shows up.
