Great Service!
I live in S. C. and was visiting my daughters in Atl when a dashboard light came on. I stopped at Lou Sobh and told the Service attendant what was happening. He checked it out immediately, fixed the (minor) problem and sent me on my way. Nice, personable and professional! His name is Garrett Stryker and he was awesome! Thx Garrett!

2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Great Customer Service and Assistance
The salesman (Jerrel) was great to work with because he helped me while he was there Orr if he was off that day. He got me a car from another store then found out there were problems and found me a car around the same price range that was newer and less miles. Thanks for everything!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

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.

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.
