Our story
At Profast Mechanics, we believe the right fix is the one you actually need, not the one that pads a bill. Ask Khan to look at your brakes and he'll tell you when they still have life left in them, then show you exactly what to watch for before you need to come back.
We handle the full range of what a car needs to keep running: oil changes, brake service, battery testing and replacement, engine diagnostics, electrical repairs, clutch and transmission work, and suspension repairs. If you show up with a part in hand or an issue we haven't seen before, we'll work with you to figure it out.
We're on Sonoma Blvd in Vallejo and happy to squeeze in a short-notice repair when your car can't wait, even on a weekend. We accept cash and Zelle, and we'll make sure you're comfortable while you wait.
What customers say
“I love Khan! He is an honest mechanic. My battery failed and I brought my car by to get him to change my battery. He tested my battery and told me I didn't need another one, then went above and beyond and took the time to educate me on why my battery was good. Khan and his team will be the only place I take my car for as long as I'm here in Vallejo.”
“We've been looking all over the Bay Area for a good mechanic and we finally found one. Our Subaru needed a new clutch and Khan quickly gave a detailed quote, then talked us through the whole process with pictures and updates. He was professional, honest, friendly, everything you want in a mechanic.”
“Fantastic work, quick, friendly and straight to the point. My pickup's leaf springs were on their last days so I called for an emergency replacement. I brought my own parts and these guys threw it together for less than Les Schwab and also faster. They didn't try to do the run-around like other shops to weasel money out of you.”
