New and used 2026 GMC Sierra 2500 trucks for sale near North Potomac, MD

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.

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.

The service team is the best I have encountered in the industry. They are true professionals and provide outstanding customer 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.

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

Could not have been any easier !!! Over all experience was great !!! Wouldn't go anywhere else. My whole family has bought cars from Criswell Chevrolet

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

Our salesman was Scott. Extremely knowledgeable and helpful. Entire experience (bought a 2026 GMC Arcadia) at the dealership was excellent. We moved quickly through the process. Will go back for future vehicles.

Great service Dina provides exceptional customer service.Her feedback is second to none.I enjoyed work with her in the future,other can learn from her . The service manager also was great.

I recieved EXCELLENT service from Mike Furman!!! He was honest and didn't even take a deposit until he had the allocation and ordered my 2026 Corvette Z06. He set me up with courtesy delivery in Colorado and made everything as easy as possible for me. His sales managers Bobby Linthicum, and Jason Witte were also helpful and available to answer all my questions every step of the way. Wyman Chow was exceptional as well coordinating the signing via FedEx and setting me up with my extended service warranties and making my purchase via wire. Criswell has an exceptional team and I will definitely refer you to anyone looking to purchase a corvette!!!

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!

My husband and I were so pleased with our recent purchase of a new truck from Koons in Clarksville. Our sales person Jack was absolutely amazing. From pricing to just plain great customer service we were so pleased. No pressure just a great deal. Thanks Jack. Will definitely share our experience with others.

We received outstanding customer service from Luis Arredondo when buying a 2023 Chevy Bolt, which I am very content with and enjoy driving. The price was reasonable. Luis was always responsive to our inquiries and focused on our needs. I also really appreciate their Sunday sales hours. Service was great in reprinting the key.

Kacey B is a fantastic Service Rep !!…No!, the BEST Service rep of my 48 years of buying GM automobiles, and One of the main reasons we like Koons! Parts Dept. and Frank also great to deal with!! And when I need both- fantastic team !! Service is always timely, job is done correctly. Nothing but kudos for this team !! A+

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!

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.

Pricing was upfront and competitive. I appreciated that they weren’t playing games to try to get me in the door - they honored their price and kept things simple.
