A customer came to us after her brakes went out on a Monday morning while her son was with her in the car. AAA sent her tow truck our way and we’re really glad they did, because we were able to fix her brakes and catch a manufacturer recall she would have never known about.

We love every chance we get to make a difference in someone’s day and keep another family safe on the road. This is why we do what we do!

Francisco is all the way into timing belt replacement, which is one of those jobs that's easy to put off. A timing belt doesn't give you much warning when it's ready to go, so staying ahead of it makes all the difference!

Charlie, Shop Manager. Part-time comedian, full-time “let’s get it DONE.” 😄🔧

Most days, he’s keeping the shop laughing with perfectly timed one-liners… but when that focus kicks in? You’ll know. The jokes pause, the game face shows up, and things start getting fixed fast.

Around here, we love both versions—but when Charlie gets that look, it’s best to just step aside and let the magic happen. 💪
