New and used 2026 Mercedes-Benz S-Class S 580 4MATIC for sale near Bannockburn, IL

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.

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.

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.

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.
