Our story
A shop built on straight answers
Advanced Mobile Auto is a car repair and maintenance shop on Landini Lane in Concord, run by Alfredo, Freddy to most of our customers. You call, you talk to the person who will actually work on your vehicle, and you get a real diagnosis with a parts list and a price before anything gets turned.
We take on the work other shops pass on. A 1992 pickup with a junkyard A/C unit and R12 lines that needed adapting to R134 was turned away by seven shops, including the dealership. It left here blowing cold the same day. When we quote a job, we honor the quote, and when we say a car will be ready tomorrow, we mean it.
Our customers tell us the shop is clean and organized and that cars come back better than they arrived: one left with a steam-cleaned engine bay it didn't come in with. We're open Monday through Friday, 8 to 5.

What customers say
“I brought my 1992 Toyota pickup in with an AC I pulled from a junkyard. 7 other shops including the Toyota dealership did not want to touch it. I brought it into Alfredo and not only was the customer service outstanding, he took the ac adapters from r12 to r134 that no shop wanted to install on my ac lines — he had my ac blowing cold same day. I will be going here from now on! 10/10 recommend”
“Took my car in here on a Tuesday at 12pm. By 1:30 the owner Freddy had already called me back stating his diagnosis, provided a parts list, everything they would do and a quote. A one day turn around was amazing! Not only is the car running amazing now, he also steam cleaned the engine bay! The price he provided was very fair and he's easy to work with. I don't always trust mechanics but he made it easy.”
“I'd been without heat in my Jeep Wrangler since 2024. Spoke to Alfredo on Friday and he said if I could get it to him Tuesday at 8am he'd take a look. I drove from Sac, got to him at 8:05. He greeted me by name. He called less than 2 hours later and said "you have heat." Best words I'd heard in a long time. Honored his quote, and did what he said he would do.”
