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.

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

My Sixth Mercedes Benz-Fantastic Cars

I service my car at BmW of Boston because they provide me with a loaner car for use while service is being performed. A much needed convenience.
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.

My Yearly service was prompt and reliable. My car was ready on time, nicely washed and cleaned. As always, Service Advisor, Jesus, was very thorough and helpful in explaining the repairs and our options.

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.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

I am extremely pleased with the customer service dept. Nathan was courteous and listened to all my questions and had the answers for me. I came in on a Saturday for express service for a dead battery and received my car back fixed in a timely fashion. I will more than likely buy my next car from flagship motors, and I will recommend them to my family and friends. Thank you very much and keep up the extraordinary service. Harry Dragonis

Great Service Excellence!!
I bought my truck 18 months ago from Anderson Auto. I have had some repairs that I was not expecting nor planned from a budget stand point. Jason had heard I was not happy and still 18 months later honored his guarantee to stand behind the vehicles he sells even beyond my warranty. I'm greatful he stood by his word and I will return for my next vehicle. I would recommend Anderson Automotive 100%
Great Vehicle
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.
