Excellent experience everyone goes above & beyond to give you the best experience purchasing your new Mercedes they make you feel cared for & truly give the best customer service. Everyone is friendly & smiles & are professional. Best experience I ever had I definitely would recommend purchasing your next vehicle with Viti Mercedes 😊

Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

Viti exceeded our expectations. Their service department went above and beyond any experience I’ve ever had with any dealership! Our convertible top was stuck in the open position on Cape Cod. The service manager Tony picked up the phone at 7:30 am on Monday, my car was in the shop Tuesday morning. Russell, our service rep, called Tuesday afternoon car was ready for pickup Thursday. To top off my experience they delivered the car back to the Cape Cod!!!!! The absolute best experience of my life with a dealership!!!

Very professional, personable and efficient dealership. They offer fair trade-in values and have great prices. Overall, highly positive customer experience!

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

The BEST dealership to have your Mercedes serviced. Russell Machado is also the BEST service advisor there is. I highly recommend this dealer for their attention to detail and their professional and friendly approach to service!

One of a kind customer service!! Great communication and very helpful! Liam Thank you for making my day!

I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

The point of contact got back to me quickly and I appreciate that. Mentioned that I would be in the area on May 24-31 to drive thge car if still available. I don't like buying sight unseen. The car looks beautiful.

This was by far the best car buying experience I have ever had, in and out in less than an hour.We walked away happy and felt very much taken care of. We would come back again and again!

I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

Excellent and on time service, Mike Robinson the service rep was very nice (as always), and a fine loaner vehicle

Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

I bought my car at this dealership a number of years ago..And coincidentally, I had a flat tire happen to me right around the corner from them. They replaced the two front tires (worn enough to merit requiring when changing one we needed to change the other). The process was quick. And while they needed to receive the right tires overnight they also cleaned the car quite thoroughly. Everyone was very nice and helpful.

When we went to the dealership we knew what we wanted and what we didn't want and Rocco was patient, answered all of questions and let us make our own decision.

5star service. Very knowledgeable and courteous. Brian Vaz was amazing. Would buy here again. They explained all my options and didn?t force anything besides what we wanted.

I had an excellent experience. My salesman was knowledgeable and helpful. I was there for a total of three hours and drove away with a Porsche Macan!

I went to get my vehicles serviced and Jesus took good care of me. Honestly I felt like home. Ask for Jesus he is the best.

Naseem was an exceptional salesperson all during the process. She picked me up at my home when I didn’t have transportation. Luckily I live fairly close. I was actually impressed with all the staff who remembered my name. I am very happy with my purchase. It’s only been a day but I will certainly keep you posted!

11/28/2025 I called Schneider at around 7:52 a.m. He then gave me the towing company’s number to arrange for the car to be towed at 8:39 a.m.
 At 9:29 a.m., Schneider called me to inform me that the tow truck had arrived at the dealership and that they were going to find out what happened with the power steering. He called me later and told me that the car was ready. Furthermore, he went the extra mile to check whether I was covered by my extended warranty. I had a great experience with Schneider. Kami P.

Stephen Leung at Mercedes-Benz of Boston is the finest sales consultant? I have had the privilege of working with either at this dealership or any dealership in past years. He is professional, extremely knowledgeable, articulate, and a pleasure to deal with it gives you the pluses and minuses and is completely honest. I highly recommend him.

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 am from out of state, and made an inquiry online. I received a prompt reply and followup from a salesperson. Although I did not make a purchase at this time, I will definitely give them another try when circumstances change.

We went in to veiw a used car. There was no sales pressure and the facility was excellent.

Manny was very helpful explaining the different options to repair my E400. His recommendations were right on track . He set up another appointment for me to keep my car running smoothly!
