New and used 2026 GMC Sierra 1500 SLT trucks for sale near Adelphi, MD

The new car manager did not beat around the bush. He gave me clean fax finance payments interest rates. It was no xxxxxxxx when you went to see this dealership is all about business and friendship.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

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.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

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

Great experience, all around customer centric team. One of the best purchase experiences I have in my many years of buying cars. I would definitely go back.

Always excellent service. Dina and her team take great care of my vehicle! Since moving to SC, I still go to Criswell for service on my car.

Javon, was excellent, he listened to everything that I wanted and was able to identify what was important to me and was able place me in a vehicle that met all my needs.

Thank you to Hamza in finance and Dave in service. Both were very knowledgeable and helpful and we were able to get what we needed done in a timely manner.

Friendly & exclent service, The service advisor was great and knowledgeable.time wise was right under the 1.5 as the told me upon arrival to the dealer.

I purchased my brand-new car in December of 2019. I also financed a service contract. Since then, my car has continued to run excellently. I'm prompted for regularly scheduled services (approx. every 5,000 miles). After scheduling my appointment and arriving on time, I was immediately checked in. I choose to wait for the service. While waiting, I am provided with a text number where I can check on the status. The work is regularly completed within an hour and a half. All of the costs have been covered by my contract. All the personnel from the check-in until the delivery after service are very knowledgeable, helpful, and friendly. There are service locations closer to me, but I greatly appreciate the service that I get at Koons Chevrolet GMC Clarksville.

This was hands down the best car-buying experience I’ve had in all my years. I’ve purchased vehicles from Mercedes, BMW, Acura, Jeep — you name it — and none of them came close to the level of professionalism, honesty, and hospitality I received at Koons GMC in Vienna, VA. The deal they offered was so incredible that I traveled all the way from New Jersey by Amtrak to Virginia. I’ll admit, I was skeptical at first because many dealerships pull bait-and-switch tactics. But not here. Saleam (Sales), Sait (Sales Manager), and Isabella (Finance) all confirmed the deal ahead of time and honored exactly what was promised. When I arrived just after opening at 9 AM, Sales was still in a meeting, but I was greeted respectfully right at the door. Saleam was paged, and the process began immediately. She welcomed me warmly, gave me a brief tour of the dealership—including the much-needed coffee lounge—and handled all the paperwork, insurance details, and my Costco rebate flawlessly. Sales Manager Sait was exceptional. He thanked me personally for my business — something I’ve never experienced from a sales manager at any dealership in the past. He even told me to call him anytime if I had questions or concerns. That level of care is rare. My experience was elevated even further by Finance Manager Isabella. Her energy was absolutely to the moon. She helped close the best deal I could find anywhere in the NY/NJ/CT tri-state area and the entire DMV region. She offered an unbeatable protection package at a discount, covering dents and mileage, and explained everything clearly and thoroughly. She also respected my time, wrapping up the paperwork quickly since she knew I had a four-hour trip back home. I cannot recommend this dealership enough. If you’re reading this review, do yourself a favor and consider Koons GMC in Vienna. I would happily send any of my friends, family, or colleagues here. They’ve earned a lifelong customer.

This was the best car purchase experience ever! Quick and smooth. No haggling straight forward and honest. Mr. Bentley went above and beyond. Great experience.

Everything went smooth and easy. The Sales Manager, Salesman, and Finance team was nothing short of fantastic. Third vehicle I bought from this dealership. If ever I have the need for another vehicle, I would check here for sure.

Atmosphere was pleasant and all of the personnel was kind and professional. Especially my salesman Earl Jones He made the whole process so easy. The other salesmen were very kind also. Koons is the way to go when buying a vehicle.

I have not been to this location in many years. I was so pleased with the level of service. The gentleman that assisted me was very helpful and explained the process of the repairs for my car. He also helped me with a rental car. I was not feeling well and exhausted but he made the process very easy and he was patient with my many questions.
