New and used 2026 GMC Sierra 1500 trucks for sale near Forest Heights, MD

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

High quality customer service and I'm very grateful and appreciative with the outstanding service that the advisor Takesha Porter rendered.

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

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!

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.

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.

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.

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!

Very helpful. Usual good service. Fully recommended. I was kept fully informed about the service and cost. No surprises. I was quickly notified about the progress of the work.

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

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

Sales persons were very informative and provided quality service. Sales manager took time to confirm eligibility for all possible rebate offers. Financing took time to answer all questions and reached out for confirmation on questions from customer.

The planning ahead and the attention to detail in the early stages of this purchase made the final paperwork and completing the purchase easy and quick. I drove from Greensboro NC, 4.5 hours away to purchase the truck. The truck and all the details were ready, I was promptly taken care of and out the door in about an hour. Had to be the easiest and fastest vehicle purchases I have ever done. Completely satisfied, and happy I chose to do business at Joyce Koons GMC. Hats off to all the team that helped make this happen.

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