When it comes to personal investments, your car is probably at the top of the list, right next to your home. Because you've invested so much money in your car, you want to make sure that it maintains peak performance. To do that, you need to make sure you put the best possible parts into it. If you've been involved in an accident, you need to ensure that genuine GM parts are used for the repairs. While aftermarket parts may save you money upfront, they're going to end up costing you more down the road. Here are three reasons you should never run aftermarket parts in your GM car.

Your Safety Systems Could Be Jeopardized

If you've been in a car accident, you want to make sure that the repairs are done correctly. You also want to make sure that your car is still safe to drive once it's returned to you. Unfortunately, if you've had aftermarket parts used for the repairs, your car might not be as safe as it was before the accident. The reason for this is simple – your safety systems can be jeopardized by aftermarket parts. Genuine GM parts are designed for safety and durability. Where GM parts contain steel components, aftermarket parts might contain plastic instead. That's a big difference when it comes to the safety systems on your vehicle.

Aftermarket Parts Might Not Be Safety Tested

When you purchase aftermarket parts, you have no way of knowing where they were manufactured or if industry standards were followed during the manufacturing. In fact, some aftermarket parts are produced illegally and without any safety testing. Installing genuine parts on your car ensures that those parts have been inspected and tested.

You Could Endure Extended Down Time

Because aftermarket parts don't go through the same rigorous manufacturing process as genuine parts do, they might not last as long. Unfortunately, that can result in extended down time for your vehicle. Saving money on the initial purchase could translate into additional costs in the way of increased breakdowns and repairs. If you're without your car for extended periods of time, you may also find yourself spending money on a rental car.

You've invested a lot of money into your car, don't sell yourself short by settling for aftermarket parts. If your GM car has been in an accident, make sure you have it repaired using genuine GM parts. For more information, contact local professionals like National GM Parts.
