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.

A great experience!
I recently purchased a used car from Fitzgerald and the experience was wonderful. The whole team was great, but we had an excellent salesperson by the name of Ernest Marshall. He was personable, professional and was able to answer all of the questions I had about this vehicle. You won't regret going to Fitzgerald and working with Ernest.

I just bought a 2020 Ford Transit from Trust Auto in Maryland, thanks to Vlad, it went well despite the fact that I live in Florida. Kevin was very nice, seemed good at his job and well spoken, good guy. Vlad was fast, professional, and made the entire process incredibly smooth and straightforward. Vlad was responsive, sent photos within minutes of the underside of the van, and we finalized the deal in under an hour. The van was exactly as advertised, and it was delivered to my home in Florida in less than a week. Vlad and Kevin have great communication, humor, and transparency made. Vlad specially made this a stress-free purchase and I feel I got a good deal. I absolutely recommend Vlad and for the Accounting Kevin, Trust Auto is a good one!

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.

Great people Great experience
We decided to purchase a couple of Jeeps. Ourisman was the only place that had the model we wanted so I decided to make the trip from NM. I thought is was a crazy idea but with the pandemic going on it seemed fitting to do something crazy. I had pleasant experience. So ended up buying 2 Jeeps and because the transport was 2 months out I flew there twice. The guys are fantastic. The price we agreed on is the price I paid. People should be able to understand the advertised price includes incentives they might not qualify for. It is the name of the game. But look at the bottom line and likely the price from Ourisman will be better than the rest. The sales person was great and Younes, the general manager, as well as Simo, the sales manager, make the buying experience pleasant.

I was interested in a Nissan NV 2500.
I was interested in a Nissan NV 2500. Viewing several of these vehicles on cars.com and other sites. I decided to make the trip to Trust Auto in Maryland from West Virginia. About a 4 1/2 hour trip. I had talked to David on the phone to make sure the Nissan was still available and explained when I could be there to look over the vehicle. We made the trip in good time only running into one delay. Upon meeting David he brought the vehicle up to the front of the dealership and told us to inspect it, which is what we did. I had two top mechanic with me. While we knew the vehicle had been in an accident, the repair work was very well done on found a few bolts missing. One in the valance and the other from the inner fender. This could have been from the accident or just from being a service vehicle. A little over 94,000 miles on it. The detail shop did a great job on their work. Very chean for sure. After running the computer test, we took the Nissan NV for a test drive. It did not disappoint. Extremely happy with everything we saw and felt during the test drive. Steering was solid and tracked well. No pull to either side while driving. Throttle response was perfect as well as the braking system. The comfort of the Nissan NV was Avery pleasant surprise. The ride was almost as good as my Lincoln MKZ, almost.😎 Much like a 2006 GMC dually I had in 2007. Very nice. When returning to the dealership myself and the two mechanics talked things over and decided to go to the next step. After a little negotiation we settled on a fair price and made the purchase. David was very kind to us and I feel like we got a great deal. We finished the paperwork and was ready to leave but we were blocked in by another vehicle. I backed back into the parking spot when one of the ladies that worked there said she would move the vehicle so we could be on our way. She came back within a few minutes moved the vehicle and with a big beautiful smile waved goodbye to us as we left. That truly made my day😇. Trust Auto in my opinion is a great dealership and when I need another vehicle, they will be the first ones I will go to. Thank you to everyone who was so kind to us while we were there and may GOD bless everyone of them 🙏✝️🙏 Jon
