New and used 2026 GMC Sierra 1500 AT4X trucks for sale near Garrett Park, MD

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.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

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

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

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.

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

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!

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

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.

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.

I?ve taken my cars to get serviced at this location for years. Most recently my new Encore GX and so far they?ve met my expectations even when there are issues they?ve been quick to solve them.

Excellent as expressed. Mr. Donovan was my advisor and he conducted himself in a manner that was extremely impressive. He was extremely knowledgeable and professional. He is a front man for this company and he represented himself very well. I appreciate this type service and will continue to return and will share my experience with colleagues.

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.

I am one to do my research for not just an appropriate vehicle, but a honest dealership. Many bait-price you into their dealership though ads, where upon entering the buyer's process become overcome with dealer fees. Yes, here they had fees, both state required and dealer processing. The difference, the dealer's fees were practical and reasonable, not overcoming of any savings offered. Too, they were openly disclosed upfront for full awareness of the cost for purchase. In addition, I was able to find a use, under manufacturer warrantied vehicle with low mileage, at a price on the low end of the fair market scale. In summary? Here you can purchase high quality vehicles at a reasonable price, while receiving respectful customer service with an honest approach?a dealership of choice.
