Used Mercedes-Benz GLS 450 for sale near Sudbury, MA under $899,990

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.

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 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.

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.

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

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! :)

I have experienced nothing but the best service and their care of the customers is beyond any other car dealership I have experienced in my life. They go out of their way to please their customers. Every employee have smiles to everyone.

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.

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 contacted them for a car listed on the Internet. It had been previously sold but they assisted me graciously and offered to find me a vehicle.

Brian in Mercedes service provided prompt and knowledgeable service and support for my Benz. 10/10.

Excellent, understanding, professional and very efficient! Great company to do business with! Will definitely go back to buy future vehicles and highly recommend them to all my family and friends! Thank you Jaime and Tim!!

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.

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.

With time running out, they went above and beyond to help me create an amazing Christmas for my wife. Got her GLS in with a photo finish! Thanks again!

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

Most of my dealings were with Chan. He kept me updated throughout the process without putting any pressure on me to buy or not to buy. I finally did purchase a2020 Fiat 124 spider Abarth. The car is everything Chan said it was. Couldn’t be more pleased.
