It is your right to have your vehicle restored back to its pre-accident condition, which means that you should always use original replacement parts made only by GM. Many insurance policies limit compensation for collision repairs by integrating aftermarket collision parts into each repair. They may cost less, but aftermarket parts do not provide the same level of original fit, form, and function as GM Collision Parts. Before agreeing to work with any shop, carefully review your insurance policy now for Original Equipment Manufacturer parts usage. If genuine parts are not specified, request a policy that states only GM Original Equipment Manufacturer parts will be used to repair your vehicle and bring your car only to a GM Certified Repair Facility.
The Choice is Yours
If another party's insurance company is paying for the auto body repair, you are not obligated to accept a repair valuation based on that insurance company's collision policy repair limits, as you have no contractual limits with that company. In such cases, you have control of the repair and parts choices, so insist on Genuine GM Parts and a GM Certified Repair Facility.
Go With Genuine GM Parts
By using inferior aftermarket parts, you might compromise your vehicle’s safety performance in subsequent collisions and diminish your vehicle’s resale value down the road. When you have the damage repaired at your local GM Certified Repair Facility using only Genuine GM Parts, you get the peace of mind of proper equipment and quality replacement parts. When it comes to collision repairs, it just makes good sense to turn to the GM-trained Certified Service experts.
GM vehicles should be fixed by GM Certified Repair Facilities, using Genuine GM Parts, because when it comes to your car, only the proper training, experience and skills will suffice.
