ABOUT US
Family-Owned. Community-Trusted.
Horsepower Auto is run by Carlos Mendez, a lifelong mechanic who believes auto repair doesn't have to mean anxiety and surprise bills. He opened Horsepower with one lift, one toolbox, and a simple promise: tell the truth, charge fair, fix it right.
Today, our team of four technicians serves the greater Denver area with the same values Carlos started with — honesty, quality, and respect for your time and budget. We're not a chain. We're your neighbors.

CUSTOMER REVIEWS
What Our Customers Say
“My check engine light came on during a road trip. They got me in same-day, diagnosed the issue quickly, and had me back on the road by afternoon. Lifesavers.”
Sarah T.Honda Civic owner“After the dealer quoted a big repair, I brought it here for a second opinion. Turned out I only needed a much smaller repair. They could have easily taken advantage.”
James K.BMW 3 Series owner“Clean waiting room, fair prices, and they actually finish when they say they will. I recommend Horsepower Auto to everyone I know.”
Linda M.Ford Explorer owner“They texted me photos of what they found under my car. I could see the worn parts myself. That kind of transparency is why I'll never go anywhere else.”
David P.Chevy Silverado owner
