Used Mercedes-Benz GLS 450 for sale near Boston, MA

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.

Very easy and enjoyable buying experience. Seamless leasing / Finance experience. Beautiful facilities and car lineup. Would highly recommend for anyone looking to purchase a luxury car.

Excellent dealership Excellent people Excellent and friendly work I would recommend this dealership to anyone!!

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.

This is the best car dealership experience that I have ever had, we were attended by David as our sales man, he was very professional, he took his time and explained and answered all our questions in the best manner, we were complicated customer and David was able to addressed all our concerns, he print out all the paper work professionally, explained us all the fees, package options, LeaveVsFinance pricing and much more, its really nice to see all these numbers printed for sure!! This dealership is honoring MSRP and internet prices! (Not like some others around in the area which are asking overprice). Our finance guy was George, very professional as well, he addressed our all concerns and we were able to get a great interest rate!!! There wasn't any pression at all from our finance and sales guy which is great. We purchased a VW atlas crossport and we are very happy with the car, This dealership is also including a 20 year 200k Miles powertrain warranty for free!!! Thank you David and George! please keep up the good work.

We called the dealership and asked about a specific vehicle. We explained that we couldn’t make it to a Boston for a while. They offered to bring the vehicle to us close to an hour and a half away and that really won us over. The vehicle was just what we were looking for and we purchased it. Thanks so much to Juan! He went above and beyond.

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 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+++++++++

The best way to start the new year - picking up my new Cadillac and working with Al P.! The transaction could not have been smoother and Al made sure I was informed and comfortable with all of the bells & whistles! Cadillac of Norwood - there is no other place where you will be treated so well!

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.

Amazing communication! Great Cars! They contacted me promptly and I was able to see the car virtually. Completed my financing application online and made my purchase remotely.

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.

Good for Travel and Towing, very convenience for every needs. It has most of latest technologies installed inside the car. Many advanced options require users to read the manual.

I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

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 service specialist was amazing. He took time with me and explained each recommended repair. He definitely made me feel like a valued customer! Thanks

Seamless purchase excellent staff very respectful great experience would definitely buy a vehicle here again

I had the pleasure of meating a sales rep named manny and he delivered just what i needed i was satisfied thanx msnny 5 stars!

This my second GL and I am very pleased with the many new options. I will need to look up and figure how to use most of the yet the manuals are easy to use. and there are videos on MB web site to help.

Ali was good. I had the financing secured online as well as a couple others to choose from that Ali provided.. Made sure the car was in tip top shape before delivery and handled everything at the RMV. Extremely satisfied with the process.

This is the 3rd one we own , we have love this vehicle since the 1st one and never have any problems thank you Mercedes

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! :)

Kyle Kelle provided me with exceptional customer service. he made the car buying experience stress-free and made it seem so simple. He took care of everything. I’m so grateful and I love my purchase.

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.

Go to Michael Robinson for service. Absolutely professional and friendly can help you save a lot of trouble and cash

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.
