Highly recommend this dealer, and Asia Allen,
Highly recommend this dealer, and Asia Allen, specifically. She helped me sort out a deal on a vehicle remotely, and it’s one of the easiest, if not easiest, car buying experiences I can recall. She’s very prompt, very friendly, made it easy to come to a fair price, and even arranged transport for me. Total white glove service, highly recommended!
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
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.

This is my second experience at MB of Westwood.
This is my second experience at MB of Westwood. The first experience was horrible, but since then many things have changed in the second experience was what you would expect. I had sales person Matthew Waugh, who was excellent, professional and helpful. The Finance director, Nichole was a straight shooter and fabulous as well. Marco, who was recently brought on in a management position in sales was the icing on the cake.

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 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
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.

Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.
High Performance And Comfortable Car
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.

Sharon Munoz was wonderful and not pressing on any aspects. She knew every detail on all the cars I test drove and it was a seamless transition. I highly recommend working with her, she will answers your texts/calls at anytime of the day. Thanks you so much Sharon!
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.
