New and used 2025 GMC Sierra 1500 trucks for sale near Adamstown, MD

I dealt with Kevin O'Connor and he was outstanding. He understood what I was looking for and was not trying to sway me one way or another, just offered courteous insight. I really appreciated the care and attention of the whole staff.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Loving my Customizers truck. Just came in for my first oil change. Sales and service is always very friendly and helpful. Logan and Kyle always make sure I am completely satisfied.

Whoa! What a great experience buying a car with Chase McCoy. From the initial introduction, through the final (Red Carpet) pictures to complete the delivery, Chase was beyond easy to work with. He was very attentive, far from over bearing, and extremely thorough. Also, Chris Gaston in (Management), structured a phenomenal deal that we were unable to refuse. Both Chase and Chris made car buying extremely easy, and most certainly a very memorable experience. When the need/want arises will not hesitate to buy from Chase McCoy again.

Without a doubt, this car buying experience stands out as the best one I've had so far! Having bought more than 10 cars in the past, I can confidently say that Ralph and Anthony were incredibly professional, honest, and patient throughout the entire process. Their approach made us feel like part of the family rather than just another customer, and they were attentive to our family's specific needs. Jessica also made the final steps a seamless process without trying to sell us things we didn’t need! We are absolutely thrilled with our new Acadia! I wouldn't hesitate to recommend Sheehy to everyone I know, and I would gladly return as a repeat customer in the future. Thank you Anthony, Ralph, and Jessica!!!

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

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!!

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.

Straightforward experience diagnosing a check engine light as a catalytic converter failure. Promptly replaced under warranty. Took only two days including shipping the new part for a discontinued car!

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

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.

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.

I recently purchased a 2023 Ford Transit from Koons Clarksville, and I couldn't be happier with the experience. Randy was my sales rep, and he was incredibly helpful and attentive from start to finish. He answered all my questions, kept the process smooth, and made sure I felt confident in my purchase. I appreciated his professionalism and patience—especially with such a big decision. The team at Koons made everything straightforward, and I’m thrilled with my new van. Highly recommend!

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.

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.

Excellent customer service. Maintenance/service was completed quickly and professionally. Customer service representative was outstanding and knowledgeable . Tracked the service process and reported the status. I will return for future services.

Customer service is always great at Criswell. They are communicative and knowledgeable. I would highly recommend them to anyone who needs their GM vehicle serviced or repaired!
