What we work on
- 01
Diagnostics
Check-engine light or a noise you can't place: we run the diagnostic, pull up the codes, and show you what's actually wrong on video before quoting anything.
- 02
Brakes
Pads, rotors, and calipers inspected and replaced, with the worn parts set aside so you can see how much life was left.
- 03
Engine repair
From gasket leaks to full replacements, diagnosed first so you know what's failing and why before the engine comes apart.
- 04
AC service
Warm air out of the vents in San Diego heat gets checked for leaks, low refrigerant, and failing compressors before recharging anything.
- 05
Smog & inspection
State smog checks and pre-purchase inspections, with any issues we find explained in plain terms before you register or buy.
- 06
Batteries & electrical
Slow cranks, dead batteries, and wiring gremlins traced to the actual fault instead of just swapping parts and hoping.

Show, don't tell
You see the worn or failed part, often on video, before we quote the fix.
Quote before the wrench
We give you a written quote after diagnosis and before repair, not after.
Urgent versus later
We tell you which issues need attention now and which can reasonably wait.
“Honest and reliable! I brought in my Mustang for an engine replacement and was back up and running in 3 days. The location is easy to find and the prices are affordable.”

“I just need to brag on Riley. I’ve had a few issues with my SL500 and every time, Riley has diagnosed and or completely taken care of the issue quickly.”

The real thing

A garage that shows you the part, not just the invoice
RGM Auto Repair works out of a plain concrete-block garage in Spring Valley, roll-up doors open to the lot, one car at a time up on the lift. Riley and the crew walk customers through what they find under the hood before touching anything, often with photos or video of the actual worn gasket, pad, or belt in question. Some jobs are urgent, some can wait a few months, and the shop tells you which is which instead of treating every light on the dash the same way. Cars come in from Spring Valley, La Mesa, and the surrounding hills, and a lot of them come back.

Questions
Will you tell me if a repair can wait?
Yes. Once we diagnose the issue we'll tell you plainly whether it's safety-critical now or something that can be scheduled for later. We'd rather you know the real timeline than get pushed into work before you need it.
How do I know what's actually wrong with my car?
We run the diagnostic, trace the code or symptom to its source, and show you what we found, often with photos or video of the part itself. You see the evidence before you decide anything.
Do you work on all makes and models?
We take on a range of vehicles, from everyday commuters to more specialized cars, diagnosing each one the same way: find the actual cause before recommending a repair.
