New and used 2025 GMC Sierra 1500 AT4 trucks for sale near Silver Spring, MD

I recently purchased a 2025 Corvette Z06 at this dealership and I had a great experience! Jack, who was my salesman, helped me and went above and beyond throughout the whole process and made my buying experience great. He was so helpful, made sure I knew everything about my car and was always there to answer all of my questions. He is one of the nicest people I have ever met, and he even personally drove the car I purchased all the way to my home in Virginia. Jack is AMAZING and I would come back just for him. Hamza was also extremely kind and helpful and very intelligent. He made sure I was informed about all finance aspects of the car and he made sure I made the right choice when purchasing my maintenance plan. He has always been so helpful and even to this day if I have any questions, he is always there to help me. Please promote these two employees because they are absolutely amazing and the stars of that dealership!

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.

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

Excellent customer service. This is the fourth vehicle purchased from them. Extremely happy with the management. I will be back in the future to purchase another vehicle in the near future.

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.

Jean is a super star and was the only reasonI ended up purchasing the vehicle. Jean listened, wasn't pushy and should give lessons to others on sales techniques. Excellent communication and great conversation. Michael is great and John was pleasant to deal with also.

James is an exceptional salesman and goes above and beyond to take care of the customer.

Sales person Mike Furman did a great job. He was professional and great to work with.

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

Mr. Malcolm Duncan welcomed me on October 14, 2024, as I was bringing my Buick Enclave for regular maintenance and repair. Malcolm greeted me, listened to my concerns and questions, and provided me with excellent service at all stages, keeping me informed until the completion of the servicing of my car. In addition, Malcolm promptly secured my transportation to and from home. I could not be more pleased with his service and assistance. I heartily recommend Crisswell dealership.

Routine service was a streamlined process from start to finish. Making the appointment through their website was a breeze. I brought my vehicle in at the scheduled time and was told the wait was going to be no more than 2 hours. Sure enough I was already on my way 90 minutes later. Speedy service. No surprises. This is how it should be done.

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

????? 5th car at this location! Another stellar experience. I will always go out of my way to drive to this location. Thanks again Koons for making it easier!

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

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.
