It was a great experience!
It was a great experience!!! They were very helpful to me going through the whole process of buying my truck!!!!! I would recommend them to all my friends!!!!!
My Sixth Mercedes Benz-Fantastic Cars
The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Best experience ever.
Best experience ever. The entire purchase process from start to completion was 5 stars and the communication was excellent. The salesperson was excellent, business office was excellent!
Great SUV
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 purchased a vehicle from Autobahn USA Dedham about a month ago and couldn't have been any happier. I worked with Peter and let me tell you he was great in all aspects. He took his time explaining everything regarding the vehicle and answered any questions my family and I had. He is extremely professional but also has a humorous side, which made the entire process even better. He was very understanding and helped us find the right car that worked with our budget. If you are considering buying a vehicle with them I recommend it, given to me in great condition. And if you want a greater/smoother experience then ask for Peter! :)
Very happy with my purchase from RBM Alpharetta.
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.

If I could give 10 stars I would!
If I could give 10 stars I would!!! I recently had the pleasure of purchasing a used Porsche, and the entire experience has exceeded every expectation I had. From the moment I began inquiring about the car, the dealership was responsive, professional, and incredibly thorough. Despite the car being located in Boston, I was initially hesitant about the logistics of having it delivered all the way to Indiana. But the dealership went above and beyond to make the entire process seamless. Timothy Klingenberger specifically was a DREAM to work with and someone I now call a true friend. He had my best interest in mind from start to finish. I can’t usually say that about any car dealership. Tim provided detailed photos and videos of the car, ensuring I could make an informed decision from a distance. The condition of the Porsche was exactly as described, and when it arrived, it was even better than expected—immaculate, with every feature working flawlessly. It was clear that the car had been meticulously cared for, and the quality of the vehicle far surpassed anything I’ve ever experienced in a used car. Not to mention and without my asking Tim included a second key fob at no additional ask or charge to ensure I had two as it would have come with when purchased new. The delivery process itself was smooth and efficient. The car arrived on time, in pristine condition, and with a full inspection report included. It was evident that the team cared about customer satisfaction and that they were willing to put in the extra effort to ensure I was thrilled with my purchase. What really stood out to me was the attention to detail and customer care Tim gave me from start to finish. I’ve owned several high-end cars, but this was by far the most seamless and satisfying purchase I’ve ever made and I can be picky. If you’re considering buying a car, I would highly recommend this dealership. They truly went the extra mile, and I couldn’t be happier with my decision.

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.

Absolutely fantastic experience
I bought a 2011 Chevy Suburban. Liam and John were fantastic. Amazing is an understatement. I did not know there are actually car dealerships anymore that go this above and beyond and as pleasurable to deal with. A+++++++++
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

First time buying a car from them and I couldn?
First time buying a car from them and I couldn?t be more impressed with how nice the sales people were, I will definitely be purchasing my next car through them,Service was great.
I’ve had many Mercedes-Benz models over the years,
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..

I usually get SUVs or Trucks from American Brands. I wanted to get my self a really nice seadan. My buddy recommended me to go to Mercedes-Benz of Burlington before I go to any other luxury dealership. His recommendation was spot-on. Dealership is beautiful with a waterfall fountain plus a nice cafe. The staff is extremely accommodating. I met Collin Stankard valet who took me to TJ a sales associate. TJ was patient and helped me find the right car for my needs. Chris Caputo GSM took the time and found the proper numbers to make me happy because I like to haggle. Then I sat down with Steve Baker a finance manager me made the paperwork easy peasy. Elaine PC had an awesome delivery for me. I learned the ins and outs of the car. Tim Martino the GM was out on vacation but made sure that everything was done properly and I was treated like a VIP. My father was in the car industry. I know the games and gimmicks the people like to run. I'm extremely happy that I only had to go to one place and had a great experience. I'm now part of the mbob family.
