New and used 2026 GMC Sierra 1500 SLT trucks for sale near Chantilly, VA

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!

Bryan DeCarlo service advisor in service was exceptional, since the moment I left my car for service and with all my concerns with warranty issues. He explained to me every step of the way, he called me every day to give me updates. I am beyond thankful I went I and had him as my advisor he told me what was needed after and felt no pressure. I am 100% happy with the service I received and from the team also working with him. He was really professional and polite and really smart at what his job is. I could keep going in bragging of the service I received. Hopefully people think same as me. Trust me I have had enough ther advisors and not even close to this kind of service.

We discovered an issue when we were buying our GMC and Lucas from the Service department was right on top of the issue. He was extremely professional and a wonderful representation of his company. He verified the issue, ordered the parts and notified us when they arrived. On the day of the appointment, he was there to ensure the repairs went extremely well and answered all questions. I just wish there were more people like him so every experience in all types of businesses would be so positive.

Great staff. Kash was great and knowledgeable. Would buy from him again and recommend him to others.

Abelilah responded quickly to all my questions and offered the best price of any Chevy dealership in the DMV- and I called at least 5 or 6. I didn't hurt that the dealership had a good selection and more coming in.

Excellent communication and quick service. No surprise fees or up-charge pressure. So much better than another local dealership.

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.

Not really sure I understand but the GMC maintenance that I bought through a different dealership wasn?t as straight forward with other dealerships but she still made it a very easy experience. She explained how the maintenance contract works so moving forward it will be easier. While I did end up paying for service I am still very satisfied with the service that I received and I felt like I was well taken care. I will continue to use this dealership due to the level of of care I received. Great service!

Good Svcs good repair, too expensive , good facilities good programming, both pre and during service??what else?.i ran out of words .:.:.:.;snuff enough shad

Donnavan did an outstanding job servicing my 2025 GMC Sierra. He was professional, efficient, and explained everything clearly. Excellent service experience — I highly recommend him!

Very helpful. Usual good service. Fully recommended. I was kept fully informed about the service and cost. No surprises. I was quickly notified about the progress of the work.

Sales persons were very informative and provided quality service. Sales manager took time to confirm eligibility for all possible rebate offers. Financing took time to answer all questions and reached out for confirmation on questions from customer.

The planning ahead and the attention to detail in the early stages of this purchase made the final paperwork and completing the purchase easy and quick. I drove from Greensboro NC, 4.5 hours away to purchase the truck. The truck and all the details were ready, I was promptly taken care of and out the door in about an hour. Had to be the easiest and fastest vehicle purchases I have ever done. Completely satisfied, and happy I chose to do business at Joyce Koons GMC. Hats off to all the team that helped make this happen.
