David was polite, professional and explained the services
David was polite, professional and explained the services to me. He also kept me informed on the status of my vehicle. Drop off and pickup of my vehicle was easy and convenient.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

If you are looking for a new or used vehicle, check out
If you are looking for a new or used vehicle, check out Autonation of Kennesaw. Roderick, Darian, and Shawn made the process easy and Hassle free. I will definitely buy here again.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I found my car on the internet and scheduled a test drive
I found my car on the internet and scheduled a test drive with Kiara. I was her first potential customer. She did a great job even though I might have scared her on the test drive. I ended up coming back after I sold my truck and was able to work a fair deal after some good negotiations. Part of my negotiation was to bring my car back and have a few things fixed on the car that I wasn’t happy about. After about a week, I was able to bring my car back down to drop off for a few days while the work was being done. I worked with their finance guy Keon. He lined me up a loaner to drive while they had my car. After about three days, the work was done and I went to pick my car up. I was very pleased with the outcome and they even fixed a few other things that we didn’t agree on but new I had questions about. They listened to me as a buyer and were willing to work with me. If you want to avoid big dealerships, they have a great inventory up nicer cars and are great to work with. I will shop with them again!

Damien Brown was super helpful on the phone and even more so in person. This dealership has a huge inventory and he was very knowledgeable about all of the different cars available. There were no pushy sales tactics, and I never felt pressured. I would absolutely seek him out again if I were in the market to buy another vehicle.

Fantastic experience with Matt W.
Fantastic experience with Matt W. (Sales). He was very helpful in my car buying process and stayed late to make sure everything went smoothly. Ashley B. (Manager) ensured my deal went through exactly how I wanted it. She crunched numbers and stayed late until the deal was finished. She was patient with me getting keys and paperwork back to her over the weekend. Very pleasant experience.
