About
Need reliable, honest work done on your car or truck? I’ve got you. I’m a one-person mobile mechanic with 2 years in business, offering quality work at fair prices—no shortcuts, no guesswork. Here’s what I can help with: - Diagnostics and troubleshooting (free with any repair) - Brake jobs and replacements - Suspension and steering work - Engine repairs - Injector replacement and maintenance - Oil changes and basic services - Custom repairs when possible I take real pride in doing the job right the first time. If something can be safely fixed without replacing parts, I’ll always try that route first to save you money. Don’t know what’s going on with your vehicle don’t worry and contact me, and I’ll take care of it.

Hired on Thumbtack

I had a great experience working with Ernesto. He is a true professional—knowledgeable, honest, and very detail-oriented. He quickly diagnosed and repaired the issues with my car. What really stood out was his willingness to take the time to discuss future upgrades and maintenance, helping me plan ahead with confidence. It’s clear he genuinely cares about his work and his customers. I highly recommend Ernesto to anyone looking for reliable and high-quality automotive service.

Reached out to Ernesto for an oil change and brake service, and everything went smoothly. He was friendly and knowledgeable, and explained what needed to be done. Got my car back to me quickly. My brakes feel great now and the pricing was fair. Overall a great experience.

Grade A guy and very professional! Repaired some problems and fixed the check engine lights on my car and we even planned some future car part installations. Would definitely recommend Ernesto!
