New and used 2025 GMC Sierra 2500 trucks for sale near Potomac, MD

Most people don?t think of a dealership for routine maintenance but Koons Manassas as an excellent place to start. Prices are fair. Service is done on time and pricing is very transparent. Give these pros a try.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

GREAT EXPERIENCE!!! Professional, knowledgeable and trustworthy, I always receive excellency services On All my car repair service.

The service team is the best I have encountered in the industry. They are true professionals and provide outstanding customer service.

The experience was very nice. The employees were very friendly and helpful. I left the dealership quite happy with the results and my vehicle.

I had a wonderful experience with Caleb Polen, both trading in my vehicle and purchasing the new one. I would highly recommend Leesburg Buick GMC and Caleb.

J. Watt was very professional and thorough making my car buying experience exceptional. He ensured that the car would be worth me traveling to see it. The car met my standards. I would recommend this dealership to others.

Matt from Koons GMC was helpful and responsive. He and the technicians got my vehicle serviced and returned to me in timely fashion. Great job!

Our salesman was Scott. Extremely knowledgeable and helpful. Entire experience (bought a 2026 GMC Arcadia) at the dealership was excellent. We moved quickly through the process. Will go back for future vehicles.

Bryan DeCarlo service advisor in service was exceptional, since the moment I left my car for service and with all my concerns with warranty issues. He explained to me every step of the way, he called me every day to give me updates. I am beyond thankful I went I and had him as my advisor he told me what was needed after and felt no pressure. I am 100% happy with the service I received and from the team also working with him. He was really professional and polite and really smart at what his job is. I could keep going in bragging of the service I received. Hopefully people think same as me. Trust me I have had enough ther advisors and not even close to this kind of service.

Excellent communication and quick service. No surprise fees or up-charge pressure. So much better than another local dealership.

We discovered an issue when we were buying our GMC and Lucas from the Service department was right on top of the issue. He was extremely professional and a wonderful representation of his company. He verified the issue, ordered the parts and notified us when they arrived. On the day of the appointment, he was there to ensure the repairs went extremely well and answered all questions. I just wish there were more people like him so every experience in all types of businesses would be so positive.

The wait was less than half an hour and the representative Matthew gave us excellent service.

Highly recommend the team of Jason "JC" Burthey (sales), Tony Blazier (sales manager), and Scott Cook (Finance) for your next car purchase. Professionals all around who made the process easy for multiple car purchases. I do a decent number of commercial/business vehicle purchases (8-10 vehicles/year), and these guys were great at cutting through the noise to get to our target and not waste my time...and with no surprises. Their consistently great inventory helps too -- kudos to the folks who manage their allotments from GMC. We've now bought four vehicles from Koons Woodbridge in the last six months, and I'd be happy to go back to them again for a personal or commercial fleet purchase. Thanks, guys!

My wife and I drove up to Koons from Ashland to look at a used car. We ended up not feeling it was a good fit, but Omar asked us to check out the terrains. We were hesitant at first but took one for a drive and ended up loving it. After a few days of thinking and some research we purchased one. Omar was such a great help, not pushy at all and very understanding that I like to do a lot of research. He was willing to work with us on price and we walked away with a fantastic deal on a brand new car. I highly recommend Omar at Koons if you're looking for a laid-back purchasing experience with no pressure. A week later Omar gave me a call to make sure everything was going well! Thanks Omar!

Donnavan did an outstanding job servicing my 2025 GMC Sierra. He was professional, efficient, and explained everything clearly. Excellent service experience — I highly recommend him!

Pricing was upfront and competitive. I appreciated that they weren’t playing games to try to get me in the door - they honored their price and kept things simple.
