New and used 2025 GMC Sierra 2500 Denali trucks for sale near Andrews AFB, MD

Koons Service Department is top notch. The ease of scheduling appointments, work is always done as promised, and on time. I recommend Koons Buick GMC to all my friends and colleagues. I wouldn’t consider taking my vehicle anywhere else. Mr. D

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.

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.

Allen is awesome! Great customer service! Knowledgeable about trucks and gives good guidance on service and repairs.

Salesman provided a very friendly/easy buying experience. Took lots of time to assist in going through key feature and answering questions.

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

We had a surprisingly (for me) good experience at Koons Chevrolet. Our salesperson Abdelilah was not pushy at all but informative. We never felt rushed, something that bugs me at a lot of car lots. Would definitely visit again.

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

I was impressed with the service we received with the dealership employees involved with the sales and trading of our vehicle.

Salesman (kash) was good. I didn?t feel pressured, environment was pleasant, my trade in was fairly priced. I will go back to the dame dealership in future when they have the type of car I want.

Bought a new car. The car salesperson was awesome. First, I called to check the availability. It was in stock; 1 hour later, it was sold and he called me to let me know. Thats okay because that car was heavily discounted. I contacted him again for a car with higher trim. Over the course of one week, he worked with his manager to get me the best deal. I bought the car the following weekend. The car salesperson showed great patience, treated my family with respect and kindness. The dealership paperwork process was straightforward. No headaches. I finished in 1 hour.

My 1st visit since 1979 well I have nothing to say except I found my new dealership. The service writer was fast and got my car in and they repaired it in no time.

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.

Mr Mario adam’s let me check out all the cars in the showroom and the lot and even let me sit in one. As a kid!!

Everyone one was very nice, waiting 2 1/2 hrs for my oil change was a little too much for me although I do realize they were very busy but they did rotate my tires and oil change that being said, they did take good care of me to make sure my suv is running great so Thank you Koons Chevrolet

I bought a new GMC AT4. I ordered it and while it took a few months, my salesman, Zak, and the Sales Manager, Josh, kept me posted along the way. The truck was just as a I ordered! Zak was very knowledgeable and walked me through all of the options. The entire sales team, including Jordan in finance, were very polite, helpful, and thanked me for my business.
