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

My service was seamless. Lee was excellent and took great care of my car and me. Touched up all my scratched wheels. Highly recommend Knauz and Lee

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.

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

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.

it was just some presales questions and they were quick to reply and offered a lot of assistance.

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

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

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

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.

Vel is a great sales guy. Very responsive and will work with the customer. We drove from MI with a trade in and they honored their offer. There were a couple minor things like steering wheel was more worn than we would have expected given the nice condition of the rest of the car. Small headliner plug interior for convertible top was missing. Other than that it was a smooth transaction.

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.

I just bought a one year old GLE 53 Coupe from michael Moran and had a great experience. He was a real professional, none of the typical car dealer nonsense. Everything was very easy and they delivered the car to me one day later. Very good experience

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.

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!!

I purchased my car three years ago, and every time I return for my service appointments, the staff is incredibly friendly. The entire experience, from making the appointment to receiving my car back, is top-notch. I have my own service advisor, Steve, who is amazing. He explains everything clearly and ensures that I understand my options. Steve excels at his job and at building a positive relationship with me. He also keeps me updated by texting while my car is in service. Additionally, the dealership recently underwent a remodel and looks fabulous. They even have a chef who prepares breakfast or lunch when it’s ordered—how great is that? Cooked to order and it’s FREE! My sales representative, Bill Harris, is honest, knowledgeable, and patient, truly an all-around good guy. He even calls me to remind me of important dates related to my car and my birthday, which is such a nice touch. I'm going to be a customer for life! Great job, everyone!

Fast and easy. All staff was pleasant, well spoken and mannered. Made an out of state purchase with a few email and phone calls. Sales person Luke was excellent.

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 enjoyed my buying experience at the dealership , sales team was great especially Jack. Vehicle features were great with clean condition , I was able to test drive and make a decision. My trade in value was great

Was looking to purchase a specific vehicle from this dealership. The one I wanted had a pending sale. The sale was not finalized and the salesman I was working with called me inmediately to inform me. I think everything went pretty fast once at the dealership.
