New and used 2026 GMC Sierra 1500 trucks for sale near Bull Run Mountain Estates, VA

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!

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

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.

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!

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.

John Barrie kept me updated on my vehicle doing a recall process if I could give him six stars I would.

Great service , no I’m not writing more words was enough Paul was a great at service

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.

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.

Great service and friendly people. Donna an is the best. The SUV is running great.

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!

Could not have been any easier !!! Over all experience was great !!! Wouldn't go anywhere else. My whole family has bought cars from Criswell Chevrolet

Not really sure I understand but the GMC maintenance that I bought through a different dealership wasn?t as straight forward with other dealerships but she still made it a very easy experience. She explained how the maintenance contract works so moving forward it will be easier. While I did end up paying for service I am still very satisfied with the service that I received and I felt like I was well taken care. I will continue to use this dealership due to the level of of care I received. Great service!
