A Chevrolet certified body shop in Ontario, CA is an auto collision center authorized by General Motors to repair Chevrolet vehicles using factory parts and factory-certified techniques. Auto Collision Group has been serving Ontario and the Inland Empire since 1987 with expert Chevrolet collision repair, from minor dents to major structural damage. We’re one of California’s few shops with genuine factory certification for Chevrolet repair, which means your vehicle gets back to factory specifications, not just cosmetic fixes.

When your Chevrolet is damaged, you need a repair center that understands GM engineering, uses real Chevrolet parts, and has technicians trained on Chevrolet-specific tools. ACG in Ontario delivers all three. We don’t cut corners with aftermarket parts or generic collision training. Your Chevrolet deserves better, and so do you.

Chevrolet Factory-Certified Repair & Technicians

Factory certification from General Motors isn’t handed out to every collision shop. It requires ongoing training, equipment audits, and strict adherence to GM repair standards. Auto Collision Group’s Ontario location holds active Chevrolet manufacturer certification, meaning our technicians have completed GM-specific collision repair training and our facility has been inspected to meet factory requirements.

Our technicians use Chevrolet diagnostic tools designed specifically for your vehicle’s systems. Whether you drive a Silverado, Colorado, Malibu, Equinox, or Traverse, we understand the structural integrity standards, frame alignment tolerances, and electrical specifications that Chevrolet demands. This isn’t generic bodywork; it’s precision repair that respects your vehicle’s engineering.

We also specialize in aluminum repair for newer Chevrolet models that use lightweight aluminum frames to improve fuel efficiency. Aluminum requires different welding techniques and procedures than steel, and many collision shops don’t invest in the training. ACG does.

Paint Matching & Factory Finish Restoration

Chevrolet paint finishes aren’t one-size-fits-all. A 2024 Silverado’s Pearl Metallic Silver is different from a Malibu’s Iridescent Pearl Tricoat, and both require specific mixing ratios and application techniques to match factory specs. Subpar paint matching leaves your repair obvious, kills resale value, and looks unprofessional. ACG uses spectrophotometer technology to scan your vehicle’s original paint and create a perfect match.

Our refinishing process follows Chevrolet factory standards for primer, base coat, and clear coat application. We sand to the correct grit, cure at proper temperatures, and apply UV-protective topcoats to ensure your repair doesn’t fade, peel, or crack. The goal isn’t just to cover damage; it’s to restore your Chevrolet to factory condition so no one can tell it was ever in an accident.

OEM Chevrolet Parts & Fighting Insurance Companies

Insurance adjusters often push for aftermarket parts because they’re cheaper. ACG refuses. We use only genuine OEM Chevrolet parts, which are manufactured to exact factory specifications. Aftermarket parts may look similar, but they don’t fit the same, don’t last as long, and aren’t covered by Chevrolet’s quality guarantee. Your vehicle deserves the parts Chevrolet designed it for.

We fight insurance companies on your behalf. When an adjuster tries to downgrade your repair estimate with aftermarket substitutes, we push back with data, documentation, and expertise. Our team knows California insurance law, and we know which carriers (State Farm, Geico, Allstate, Progressive, Farmers, USAA, AAA, Mercury) try to cut corners. We work with all of them, but we never sacrifice quality to make their margins fatter.

Your Chevrolet’s safety depends on structural integrity and part compatibility. OEM parts guarantee both. That’s non-negotiable at ACG.
