About Us

A shop that
treats your car
like its own.

R & M Auto Electric has been a cornerstone of the San Diego automotive community for over two decades. Located on National Avenue, we've built our reputation on one simple principle: do the job right, the first time, and be honest about what your vehicle actually needs.

We specialize in automotive electrical systems — the complex networks that modern vehicles depend on — but we're equally comfortable with general repair and maintenance. Whether you're driving a domestic sedan, a European import, or a work truck, you'll get the same thorough, no-surprises service.

Our approach is straightforward: we diagnose carefully, explain clearly, and only recommend what will genuinely improve your safety, reliability, or peace of mind. No upselling. No unnecessary parts. Just honest work at a fair price.

Why Choose Us

Built on trust,
reinforced by results.

Honest Diagnostics

We tell you what's actually wrong — not what's most expensive to fix. If your car doesn't need a service, we'll say so.

On Time, Every Time

We respect your schedule. You'll know when your vehicle will be ready, and we'll communicate if anything changes before then.

Fair & Transparent

Clear estimates before any work begins. No hidden fees, no surprise charges. The price we quote is the price you pay.

Testimonials

What our
customers
say.

"I brought my truck in for an electrical issue that two other shops couldn't figure out. R & M had it diagnosed the same day and fixed it that afternoon. Fair price, no drama — exactly what you want from a mechanic."

— Verified Customer, San Diego

"Finally found a shop I can trust. They explained exactly what was wrong with my car's alternator and wiring, showed me the worn parts, and didn't try to sell me anything I didn't need. That kind of honesty is rare."

— Verified Customer, San Diego

"My European car has some quirky electrical gremlins, and every shop I'd visited before gave up. R & M tracked down the issue in under an hour. They clearly know what they're doing with complex wiring systems."

— Verified Customer, San Diego
