Honest diagnostics and fair prices, every single time
Our story
We're a full-service auto repair shop in Santa Clarita, working on everything from daily commuters to classics and European imports. Whatever's under the hood, we start with an honest diagnosis before any wrench turns.
Our customers know us for telling it straight. If a repair isn't worth the cost, we'll say so instead of running up the bill, and if we can get you back on the road the same day, we will.
Led by Shy, our team has built its reputation one honest conversation at a time, the kind of shop you call before you decide whether that repair bill is worth it.
What customers say
“Ace Auto made it quick and easy to replace my battery in my cargo van. A few other places turned me down because the battery is located under my driver seat, and I needed to remove a steel cargo divider behind the seat to access the battery. I braced myself for an ordeal, but Shy and the receptionist made the whole experience simple and fast. Great service, and the price was great compared to what I faced in norCal.”
“Shy is a very honorable man. My car engine had a catastrophic failure. I took it to his shop to get a diagnostic just to weigh my options. He didn't charge me for what we both already knew: drained oil, found metal in the oil, and showed me it.”
“Ace has handled all my automotive repairs on my 95 Bronco and my Porsche. I trust Shy more than I trust the dealership. Honest and fair pricing across the board.”
