New and used 2025 GMC Sierra 1500 trucks for sale near Dulles Town Center, VA

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

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.

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.

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!!

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.

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!

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

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.

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.

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

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!

I flew all the way to Virginia from Michigan because of the great deal I received on a 2019 ram 2500. Beautiful truck one car owner. Drove it back ran perfect. Jimmy was my salesperson. He is the best. 5 stars for Jimmy!!!!

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

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.
