Commercial Service & Parts in Tustin, CA

At Tustin Buick GMC, we understand that a work truck sitting in a service bay isn't earning money. Your fleet is the backbone of your business, and our job is to keep that backbone strong. We are your local resource in Tustin for maintaining the GMC commercial vehicles that power industries across Orange County.

Specialized GMC Commercial Service

Commercial vehicles work harder than the average daily driver, and they require technicians who understand that workload. Our service team is trained specifically on GMC engineering.

We service the full lineup of GMC commercial inventory, including:

Whether it is routine maintenance like oil changes and tire rotations, or more complex engine and transmission repairs, we have the tools and the space to handle your fleet.

Genuine GMC Parts

When you replace a part on a work truck, you need it to last. We stock and sell Genuine GMC Parts and accessories. These components come directly from the manufacturer and are designed to fit your specific vehicle perfectly. Using the right parts preserves the factory warranty and ensures your vehicle performs exactly as it was designed to.
