A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

My wife and I drove up to Koons from Ashland to look at a used car. We ended up not feeling it was a good fit, but Omar asked us to check out the terrains. We were hesitant at first but took one for a drive and ended up loving it. After a few days of thinking and some research we purchased one. Omar was such a great help, not pushy at all and very understanding that I like to do a lot of research. He was willing to work with us on price and we walked away with a fantastic deal on a brand new car. I highly recommend Omar at Koons if you're looking for a laid-back purchasing experience with no pressure. A week later Omar gave me a call to make sure everything was going well! Thanks Omar!

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!

I purchased my brand-new car in December of 2019.
I purchased my brand-new car in December of 2019. I also financed a service contract. Since then, my car has continued to run excellently. I'm prompted for regularly scheduled services (approx. every 5,000 miles). After scheduling my appointment and arriving on time, I was immediately checked in. I choose to wait for the service. While waiting, I am provided with a text number where I can check on the status. The work is regularly completed within an hour and a half. All of the costs have been covered by my contract. All the personnel from the check-in until the delivery after service are very knowledgeable, helpful, and friendly. There are service locations closer to me, but I greatly appreciate the service that I get at Koons Chevrolet GMC Clarksville.

This was hands down the best car-buying experience I’ve
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 have not been to this location in many years. I was so pleased with the level of service. The gentleman that assisted me was very helpful and explained the process of the repairs for my car. He also helped me with a rental car. I was not feeling well and exhausted but he made the process very easy and he was patient with my many questions.

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.
