New and used 2026 Mercedes-Benz S-Class for sale near Carol Stream, IL

Sales rep (Kenn) and GM (Bradley) were awesome to work with. Just the kind of buying experience everyone is looking for. Highly recommended!

One of the best dealerships in Chicagoland Walter Salcedo amazing person very professional, knowledgeable, and will strongly recommend Walter to my friends for new sprinter.

This is the third S-class Mercedes I have purchased from Mercedes-Benz of Westmont and I could not be happier. Going through the purchasing process was a delight because Kimberely Cager, my Sales Rep, and the sales management team made me feel better than just a valued customer. The real test, however, came when driving the new 2025 Mercedes S580. The supreme road handling and comfortable seating were nothing short of spectacular, and the many options like the integrated toll system (driving through tolls of different states has become hassle free), Apple CarPlay, and several driver-assist features has enhanced my driving experience. While understanding how to use and benefit from the many new features and options was a little daunting, Kimberely and the Product Concierge, Damir Oliynyk, have eased my doubts, and I?m looking forward to a long multi-state road trip.

Valerie is a pleasure to work with. she?s very helpful and very attentive to our needs. She takes a complete look at our auto needs and never oversells services that we don?t need.

Earl was outstanding, he and the rest of the team found a solution for us an we are very happy with our decision to buy our GLE.

Very kind and caring . Helped alot to make the deal. Salesman was kept me informed. Lending Maneger also put extra effort to make the deal.

The loaner is a very convenient option during the timely completion of the new brakes and a repair. We feel very confident using the Service Dept at this location.

I had an outstanding experience at Mercedes-Benz Naperville working with Abraham during my recent vehicle purchase for my wife. From the very beginning, he exceeded my expectations in every way. Abraham was incredibly attentive, really listening to what I was looking for and helping me find the perfect vehicle without any pressure. His knowledge of the Mercedes-Benz lineup was impressive - he explained all the features clearly and made sure I felt completely comfortable with my decision. What truly stood out was his follow-up after the sale. Abraham checked in to ensure everything was going well and even went out of his way to resolve a minor issue I noticed after taking the car home. That level of dedication is rare and truly appreciated. I would highly recommend Abraham to any friend or family member in the market for a car. His professionalism, expertise, and genuine care made this transaction a great car-buying experience.

Mercedes c class. I believe this is the 3rd car I have purchased from Autohaus. Very comfortable feeling

I absolutely love my brand new E350!!! The dealership was excellent. I felt like I had a trusted advisor in Liz! I would highly recommend her if you’re looking for your next Mercedes-Benz!!

For over 10 years and three Mercedes, I always go back and I am never disappointed! I highly recommend this dealer for both Sales and Service.

This is one of the best Mercedes dealerships if not the best in the Midwest region. They ALWAYS do a professional job and take good care of me

I have purchased vehicles from many different dealerships, AutoHaus is by far the best. They treat you like you actually matter to them.

The dealership contacted me and followed through on everything I asked and needed of them. Great overall experience.
