Used 2024 Mercedes-Benz GLS 450 for sale near Marietta, GA

Vadim changed my opinion of car salesmen. He was professional and went above and beyond. The whole process was seamless and the first enjoyable experience I have ever had when purchasing a car. Thanks to everyone at RBM.

My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

I had to bring my car back too many times for the same tire balancing issue. It was finally fixed. I don?t believe they were doing any quality inspections like test driving the vehicle to see if the issue was corrected.

My service from Andy Sayers at RBM of Alpharetta was excellent -- and continues to be after the purchase. We visited a few other Mercedes dealerships first before meeting Andy at RBM of Alpharetta; there was no comparison. Andy was patient, extremely knowledgeable and not once did we feel any pressure to buy. It was a truly genuine and consultative experience from start to finish. I now have the perfect car for me thanks to Andy and RBM.

My service advisor Christie Hicks always delivers the BEST service possible. Definitely makes any service issues easier.

Friendly service, knowledgeable, work done well. I would have them service my Mercedes in the future.

I am always very happy with the superior customer service I received. Thank you Bobby Waites.

Awesome service from all areas. All employees made our purchase easy. We really even enjoyed the waiting to see the deal through. Mr. Tyler Simmons is a stellar salesman.

After entering my 2020 E450, I got a display message that said "12V Battery. See Operator's Manual". Sent a quick note to Mitch Griffin thinking after 5 years a new battery was probably needed. He responded and after contacting RBM, Jordin Mendez was dispatched to my house. In about 20 minutes, the battery was replaced. Great job by Mitch, Jordin and my phone contact at RBM. Much appreciated!

Wonderful experience. I did a fly-n-drive. Bought the car sight unseen and everything came together without a problem. The staff was helpful and efficient.

Jason Friedman did an excellent job moving me from my Lexus into my new Mercedes. His knowledge and information was outstanding. I came in just to look and wound up getting a hybrid plug-in which I now love driving. My entire driving experience has changed for the better!

Had a fantastic experience buying a plug-in hybrid from RBM of Atlanta. Jason Friedman was knowledgeable, patient, and made the whole process seamless. Since the car was a gift for my daughter’s 16th birthday, Jason even surprised us by putting a big bow on it — such a thoughtful touch! Highly recommend both RBM and Jason

DJ (Demetris) delivered my new car to me in Canton from the Automax in Lilburn, He was a delight! He was very professional, friendly, honest, knowledgeable, and polite. I love my new car! And, we are very grateful how D.J. made the testing and buying process painless. We are also happy to have gotten to meet this very nice young man.

Mr. Sixx is first rate. He is professional and attentive. He listens to the customer and works to address the customer's issues.

I got a fair price on my car and it was exactly as they described it. Russell and Sal were very easy to work with. I would buy from them again!

The car was great! The salesman was very helpful also. When I got it home, I had a couple issues which the sales manager took care of right away! I will definitely consider buying another car from them!

Just wrapped my 2nd purchase with RBM. Eric Koenigsberg was, once again, a pure delight. Eric is a walking historical encyclopedia of both the MB brand and all the steps necessary to purchase/lease a car from MB. The entire experience from the moment I walked in the door to the red bow on top at signing, every detail was considered and my expectations exceeded. RBM and Eric have a lifetime customer in me!

Had a great experience buying a used car at RBM of Alpharetta from Rich Alder last week! Rich made the process easy and pleasant, provided the information that I needed, and took the extra steps needed to get me the car in the timeframe I needed. Would definitely buy from Rich at RBM of Alpharetta again!!
