Saw the Ad from Rick Hendrick in re a Porsche Cab for
Saw the Ad from Rick Hendrick in re a Porsche Cab for sale on Facebook. Good price, good looking car. Bought it and the experience was delightful. Hassen Beshir, my salesman, treated me like Royalty---going so far as to drive me to my bank for a check. I would easily give the dealership a 10 Star rating...but the limit is 5. Keep up that level of satisfaction and the Georgia folk will be beating on your door. Sincerely, Mike Eberlein
This truck has a jerk when changing gears sometimes.

Highly Professional and Honest Staff The team at Cobb
Highly Professional and Honest Staff The team at Cobb Luxury Cars was extremely professional and honest. They helped me purchase a beautiful Lexus ES350 with a reasonable down payment. I also got a 4-year extended warranty through them, and when I needed to file a claim, all the repairs were fully covered with $0 out of pocket. Big thanks to the Cobb Luxury Cars team for making the entire experience smooth and stress-free!

Scott S.
Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!

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!
