Antioch's Most Trusted Auto Repair Shop

Auto Diagnostic & Repair, Antioch is a full-service mechanic shop. Not only are we prepared to take on any type of mechanic work, but we also promise to fix what other shops can't! My name is Brian Bellante, and I've been running this shop since I was 25 years old. In that time, my customers have brought in vehicles with just about every type of problem imaginable. Visiting an auto repair shop isn't going to help if the job isn't done right the first time. You need a mechanic you can trust, and you've found one.

We have two locations to serve you, our Antioch location, as well as our Brentwood Repair Shop. Visit one of our shops today for the best deals on parts, auto repair
