Everyone at the dealership was friendly and professional.
Everyone at the dealership was friendly and professional. Reva handled my purchase for my first luxury brand vehicle and is absolutely amazing. She made it all come together smoothly and was a joy to work with. It’s the third vehicle someone in my family has bought from her and we will keep coming back!
A Dream Car
This is my 5th Mercedes and by far the best car that I have ever owned. The technology and interior are amazing. The best feel of the road of any past Mercedes.

"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!

Overall it was a good deal for me.
Overall it was a good deal for me. The dealer made promises and kept them. The Tesla is great! The price was good. However, I felt the dealer fees were ridiculous and they insisted I give them thousands above the actual registration and taxes. Though I was able to recover the excess taxes/registration withheld, it felt very much like the used car salesman treatment. I would recommend the dealer, but be prepared to play reindeer games. If you do not like these games, buy your used Tesla directly from Tesla.

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.
