Kevin Bacon is reliable and trustworthy. I depend on his expertise for my 2006 Buick Lucerne to operate safely, reliably and efficiently.

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+

Brian was great to work with no pressure to buy, Told him what i wanted and he was great at making it happen, He wants me to call if any problems so that we are happy, Paper work was quick and painless, Love my new Yukon Denali,

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.

Recently I took my 2011 terrain back for repairs for the 2nd time. After facing a bill of $492.00 Mr. Bacon understood my problem and told me "don't worry , the parts are on the way and your window will be fixed. He later told me that they want me to pay $100.00. I told him my 1st visit was within my warranty and I shouldn't even have a bill. Later he came back and told me "you're good". I thanked him for his services. I will call Mr. Bacon for future services.

The salesmen and the people there we're excellent, but unfortunately the car it was not in good enough shape that I could purchase it. It wouldn't pass inspection

Great service , no I’m not writing more words was enough Paul was a great at service

Great service and friendly people. Donna an is the best. The SUV is running great.

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.

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.

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.

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
