From the business
In the shop's own words: “Real repairs, no runaround”
G&C Brothers Auto is a Pomona shop built around one idea: you should understand what's happening with your car before you pay for it. Guillermo and his team walk customers through every issue in plain language, whether it's a routine oil change or a full engine rebuild.
We handle everything from daily maintenance to major mechanical and collision work, and we treat every vehicle that comes through the door with the same care. Customers have trusted us with everything from work trucks to a Porsche 911. No inflated estimates, no surprise charges, just honest work delivered on time.
Our customers keep coming back because we keep our word. When we say your car will be ready, it's ready, and we keep you updated the whole way through.
- Clear, honest explanations of every repair
- Handles major repairs: full engine rebuilds to collision work
- Comfortable, welcoming shop and waiting area
