About Us

Built on honest work and Marlborough pride

Castro Auto Repair started with a simple belief: every driver in Marlborough deserves a mechanic they can trust — someone who tells you what you actually need, not what's most expensive.

Located right here on Mechanic Street, we've grown from a one-bay operation into a full-service shop because our neighbors keep referring their friends and family. That kind of reputation isn't bought — it's earned, one honest repair at a time.

We service all makes and models, from daily commuters to weekend projects. No job is too small, and no question goes unanswered.

Testimonials

Words from our neighbors

"I've been bringing my cars here for years. They always explain what's wrong, show me the worn parts, and never try to upsell me on things I don't need. That's rare."
