From the business
In the shop's own words: “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.
- Quotes honored, no run-around
- Same-day and next-day turnarounds
- Work other shops turn down
