My Mercedes Benz SUV
I am a senior citizen and I want to feel secure while driving, and the SUV gives me that. I am on the short side so getting in and out was a new experience for me, but I learned how to manage it. Once, I found the seat setting the visibility is exceptionally good. It handles nicely on the road with quick pick-up, and the gas mileage is about average.

ROCKING MY SABLE BROWN LEATHER SEATS!
I'm not new to the Mercedes brand, as this is my 4th. This is, however, my first try at the Mercedes SUV. So far, I'm extremely happy. Favorite feature has to be the camel leather seats...an impressive update from the MB-Tex.

My Beautiful Chrysler 200
After the horrifying wreck I thought I could never love another car like the last one. Then the fabulous sales staff at Carmax Kennesaw helped me find My beautiful Chrysler 200. She purrs like a kitten and handles like a dream. I couldn't be happier.
Pleasant drive, but not driver friendly.
A pleasant driving car. Very dependable. But, in my opinion, not very user friendly. The controls for features like like wipers, lights, and GPS are complex and buried under layers. The GPS took me over a route that was 1 hour longer than normal on a 5 hour trip because GPS had avoid carpool lanes turned on. Had to call MB at an 800 number to find out the feature even existed. Also, I HATE the run flat tires.

GLC Coupe
I bought the GLC Coupe with the AMG package and it’s the nicest car I have ever owned. The unique two tone (black and cranberry) interior definitely sets it apart from other cars.

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!

Absolutely thrilled with my experience at Gravity Motor in Marietta. I can't thank Aryan enough! From the start, Aryan was incredibly helpful and attentive to show me all the functions of the car. His communication was top-notch throughout the entire process, and he made sure everything was seamless. I truly appreciate his dedication to finding exactly what I wanted, and I’m beyond excited with my new vehicle. Highly recommend Aryan and the team at Gravity motors!

I reached out to Platinum Cars Marietta about a BMW M850i
I reached out to Platinum Cars Marietta about a BMW M850i they had in their inventory, and I was thoroughly impressed with their professionalism and responsiveness. Jason Bush and David Patel promptly answered all my questions, providing clear and transparent details about the car and its pricing. Unfortunately, we couldn’t finalize the deal as the vehicle had a damaged part that they weren’t able to replace, but they did offer me a small discount to accommodate the issue, which I genuinely appreciated. However, since I’m investing over $50K in a car, I preferred to have it delivered fully fixed, so I decided to put the purchase on hold to explore other options. Despite this, I truly valued their transparency, urgency in addressing my concerns, and overall customer service. If you’re looking for a dealership that communicates well and is upfront about their inventory, I’d highly recommend Platinum Cars Marietta.

Was provided good service with them.
Was provided good service with them. I went to check out a Nissan Sentra for my daughter but came out with 2020 Kia Soul which was better/ comfortable car. Smooth finance team and process. My only advice is if you buy a Kia make sure you know if your current insurance will cover the car and look at the cost. That was my mistake (it was on a Sunday) because I was told things were good with insurance company's covering Kia. I was going to return the Kia and get something else because they don't have a return policy. But, my daughter loves the car but will trade it in about 5 months and get something else from Atlanta Used Cars.
There are 20 matching cars close to your year range.
