"I recently purchased a car from Autobahn Dedham, and I couldn’t be happier with the experience. From the moment I walked in, the salesman, Peter, was incredibly helpful and knowledgeable. He took the time to understand my needs and budget, and guided me through every step of the process. There was no pressure, just honest advice and great customer service. The car selection was excellent, and I felt confident in my decision. I highly recommend Peter and Autobahn to anyone in the market for a new vehicle!

I recently took my car in to have some issues checked out, and Asif was extremely helpful throughout the entire process. He took the time to explain everything to me in detail and guided me on the steps I should take to prevent any further damage to my car. I really appreciated his thoroughness and excellent customer service. It was truly a ten out of ten experience, and I highly recommend choosing him as your service advisor!

Best buying experience I have had in a long time.
Best buying experience I have had in a long time. Found the car online and hashed out the details via text and phone, so when we picked up the vehicle, we were in and out in under an hour. I read some great reviews for Bentley Indianapolis and some not so good, so I got scared...initially we were going to have the car shipped to our house, so I decided going there in person was best. I found the people working there very nice and not pretentious. Our car was in great condition and was exactly what was described online and in the video/photos.

I traded my 2014 ML350 and bought a 2024 GLE 350. Service and sales were exceptional Brandon Gates really impressed us with his knowledge of the new software and controls. He provided very personalized service and we have reached out to him a few times since and got quick results. I highly recommend Chapman Mercedes on Grant in Tucson particularly Brandon at Sales and Lucky Luechtefeld as service representative.
