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

Excellent as expressed. Mr. Donovan was my advisor and he conducted himself in a manner that was extremely impressive. He was extremely knowledgeable and professional. He is a front man for this company and he represented himself very well. I appreciate this type service and will continue to return and will share my experience with colleagues.

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.

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.

I have leased 3 cars consecutively from Auto Nation in Laurel MD. I have always had a stellar experience when Keith Allen, Sales Manager: Farid Saidi, Sales Rep: Travis Jenkins are working with me. These guys are excellent! Always get things done and give the best quality of service!

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.

Friendly & exclent service, The service advisor was great and knowledgeable.time wise was right under the 1.5 as the told me upon arrival to the dealer.

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!!!

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+

Scott was awesome to work with. Very knowledgable and help full without being pushy. The dealership had a great selection of SUV's, so we had plenty to choose from and we are very happy with our selection as well as the whole process from sales to finance. All a great experience and that doesn't seem to happy often anymore.

I do not have a review. your finance person was interested in giving us a higher interest rate. may be they make more money as such

The new car manager did not beat around the bush. He gave me clean fax finance payments interest rates. It was no xxxxxxxx when you went to see this dealership is all about business and friendship.

This was hands down the best car-buying experience I’ve had in all my years. I’ve purchased vehicles from Mercedes, BMW, Acura, Jeep — you name it — and none of them came close to the level of professionalism, honesty, and hospitality I received at Koons GMC in Vienna, VA. The deal they offered was so incredible that I traveled all the way from New Jersey by Amtrak to Virginia. I’ll admit, I was skeptical at first because many dealerships pull bait-and-switch tactics. But not here. Saleam (Sales), Sait (Sales Manager), and Isabella (Finance) all confirmed the deal ahead of time and honored exactly what was promised. When I arrived just after opening at 9 AM, Sales was still in a meeting, but I was greeted respectfully right at the door. Saleam was paged, and the process began immediately. She welcomed me warmly, gave me a brief tour of the dealership—including the much-needed coffee lounge—and handled all the paperwork, insurance details, and my Costco rebate flawlessly. Sales Manager Sait was exceptional. He thanked me personally for my business — something I’ve never experienced from a sales manager at any dealership in the past. He even told me to call him anytime if I had questions or concerns. That level of care is rare. My experience was elevated even further by Finance Manager Isabella. Her energy was absolutely to the moon. She helped close the best deal I could find anywhere in the NY/NJ/CT tri-state area and the entire DMV region. She offered an unbeatable protection package at a discount, covering dents and mileage, and explained everything clearly and thoroughly. She also respected my time, wrapping up the paperwork quickly since she knew I had a four-hour trip back home. I cannot recommend this dealership enough. If you’re reading this review, do yourself a favor and consider Koons GMC in Vienna. I would happily send any of my friends, family, or colleagues here. They’ve earned a lifelong customer.
