We received outstanding customer service from Luis
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.

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.

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.

Honest Dealing
I am one to do my research for not just an appropriate vehicle, but a honest dealership. Many bait-price you into their dealership though ads, where upon entering the buyer's process become overcome with dealer fees. Yes, here they had fees, both state required and dealer processing. The difference, the dealer's fees were practical and reasonable, not overcoming of any savings offered. Too, they were openly disclosed upfront for full awareness of the cost for purchase. In addition, I was able to find a use, under manufacturer warrantied vehicle with low mileage, at a price on the low end of the fair market scale. In summary? Here you can purchase high quality vehicles at a reasonable price, while receiving respectful customer service with an honest approach?a dealership of choice.
