Great Experience!
We had worked with Justin Reid in the past when purchasing a vehicle and were so pleased that we called him again for another one. Despite all the covid restrictions, our experience was great and we were extremely pleased with the way he handled our transaction. Business manager Jim Schaffer also made all the paperwork that is necessary go quickly and smoothly. We will definitely recommend this dealership to our friends.

As a return customer with Mercedes-Benz of Hoffman
As a return customer with Mercedes-Benz of Hoffman Estates, I am very satisfied with the customer service throughout the dealership. Worked with David Bennett on my trade-in and his expertise helped me to understand and narrow down my vehicle choice. The entire Team was a pleasure to work with and they got me out the door quickly with my new GLE.
