Welcome to the Parts Department at Koons Woodbridge Buick GMC. We know many of our customers enjoy working on their vehicles themselves. You might want to change the oil in your Envision or accessorize your Sierra. Either way, we have your best interests at heart. That's why our parts department technicians won't try to discourage you from servicing your Buick or GMC yourself, only encourage you to use OEM parts. 

Why Use OEM Parts

The difference between Original Equipment Manufacturer parts and aftermarket parts can be significant. The original manufacturer made an OEM part to fit the vehicle to the exact specifications in both dimensions and functionality as the day the car rolled off the assembly line. 

Aftermarket parts often get manufactured to fit several different vehicles, sometimes even across brands. This approach can lead to poorly-fitting and functioning parts. Aftermarket parts don't go through the rigorous certification process that OEM parts must pass. In the end, you might save a few dollars on an aftermarket part, but if it doesn't fit right, work properly, and wears out faster, you'll be back making the same repair again sooner.

The same holds for accessories. We stock an expansive inventory of genuine OEM parts and manufacturer-approved accessories for Buick and GMC vehicles. If you have the part number, you can search for your part online. If not, our expert technicians can help you find the part you need. Just give them a call at 703-494-7121. If for some reason, we don't have your part, we can order it for you. In some cases, we can get it on the same day.

Ordering Made Easy

Our online parts ordering system allows you to quickly and easily place an order for parts. Whether you need new tires, a set of spark plugs, or something more obscure, you simply place the order online, and our parts department will take it from there.

You'll receive a confirmation of your order via your preferred contact method. Should our technicians need more information, they will reach out to you with follow-up questions to ensure we get the proper part for your Buick or GMC vehicle. Once we have collected your ordered parts, you'll receive a notification. 

Factory Certified Technicians

All of our parts and service technicians undergo extensive factory training in all parts and repair processes. We know it can sometimes be confusing to find the right part for your weekend repair job. Our technicians can help you identify and order the correct part for the job, saving you time. Some jobs require special tools, and we can help with those, as well. We encourage you to lean on our factory-trained staff and ask any questions you might have because we want your Buick or GMC vehicle to operate at its peak performance.

Some jobs can be difficult, and we understand this. Don't be afraid to contact us if you need a little help. Maybe the repair requires more time than you anticipated, or perhaps you don't have all the right tools. You can schedule service online even if you've already started the job. We're here to help, any way we can.
