I just bought my 2017 corvette grand sport two weeks ago.
I just bought my 2017 corvette grand sport two weeks ago. I flew in from New York. I can’t say enough good things about the process. We worked with Armin, he was top notch. He made every aspect about buying this car seamless and easy. He even arranged an Uber to pick me up from the airport to bring me right to the dealership. We just adore our new car. It’s perfect!! A million thanks 🙂 Joe and Denise

Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

I found a vehicle at Nexton on Carguru.
I found a vehicle at Nexton on Carguru. Gytis was the salesman that I worked with through the entire process. Gytis was professional, responsive, accessible, patient, and accommodating to my request as I examined the vehicle. When I decided to purchase the vehicle the process went smoothly and quickly. The vehicle was transported and the driver contacted me and informed me on delivery time. When the vehicle was delivered it was all that it was sold to be. I wanted to take time and submit this review because I understand the desire that a customer has to deal with a reputable dealership. Big thanks to Nexton Motors.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

I wanted to get a car fairly quickly and knew what I was
I wanted to get a car fairly quickly and knew what I was willing to spend. My salesperson Paolo was extremely helpful and found me my car in the color I wanted in less than a week. To my surprise, the package I purchased even came with several bonus accessories for protecting the interior. Paolo took his time with me and explained every feature in the car (even after closing), which was amazing since the manual looks like an encyclopedia. The dealership followed up later with a Zoom call to answer any additional questions I still had and they’re sending me a free gift! Overall, I would absolutely shop here again and recommend this dealership to my friends!
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

I was looking for a 2022 Navigator and Driven Auto had
I was looking for a 2022 Navigator and Driven Auto had the only one in a 300 mile radius for a competitive price. The pictures of the vehicle were excellent, so I requested more info and their salesman Basil got back with me. He was extremely helpful and even checked to see if I could reserve the vehicle since I was out of state and it was Saturday and couldn't get into the dealership until Monday. I scheduled a trip to the dealership and let Basil know. When I got to the dealership, the car was washed and ready for me. The detailing was top notch. Basil was helpful and not pushy at all. He answered any and all questions and worked with my bank to get the purchase finalized. When the paperwork was signed, they didn't try to sell me a bunch of extra things. I really appreciated that. Overall it was very pleasant experience and everything went smoothly. The price was very competitive across 3 states, and Basil was very helpful and pleasant to interact with. I saw several reviews complain that Driven Auto didn't hold a car and sold it before they got there, so yes it really is first come first serve, but to me that is completely understandable and was communicated very clearly to me. 5 out of 5 would buy there again.

Vel is a great sales guy.
Vel is a great sales guy. Very responsive and will work with the customer. We drove from MI with a trade in and they honored their offer. There were a couple minor things like steering wheel was more worn than we would have expected given the nice condition of the rest of the car. Small headliner plug interior for convertible top was missing. Other than that it was a smooth transaction.
