Our story
Mario's Mobil Auto Services is built on a simple idea: tell customers the truth and fix the car right. Whether it's a clutch replacement, a same-day gasket job, or a brake service, we walk you through what actually needs to happen and what can wait.
We don't push work you don't need. More than one customer has come in expecting a bill and left with a free fix, because the job was quick and the honest answer was the right answer. When something's outside our expertise, like exhaust work, we'll say so and point you to someone who can help.
We also come to you. If your car won't start or something's off after you've been working on it yourself, we've driven out to homes to diagnose the problem on the spot, tools in hand.
What customers say
“Mario is a true master of his craft! Very reliable, honest, and reasonable. Valve cover gasket replacement done same day and had my car back by the time I was off work.”
“Mario let me know of future issues I may have but never pushed on unnecessary issues. I absolutely recommend Mario and will continue to go to him and spread the word of an actual honest mechanic.”
“Mario's is the best. He fixed my wife's rear view mirror for FREE. Other auto repair places would have charged me for a new part plus labor. The guy is very honest and will save you money.”
