New and used 2025 Mercedes-Benz GLS 450 4MATIC for sale near Bannockburn, IL

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

Great experience as soon as I walk in every one was friendly and helpful. I recommend this dealership 100%

Extremely friendly and professional people. I would buy from them in the future.

Great service as always. Really liked Francisco. He was very personable and extremely helpful. Very easy to work with. And that's all I have to say.

We stopped into Mercedes of Westmont as a second stop in our search for a new car. I am not really a fan of buying new cars, we typically buy a car and drive it until it’s dead, just so we don’t have to go thru the whole purchasing process of getting a new car. Chris at Mercedes of Westmont has completely changed my outlook on buying new cars! He is very professional, but yet relatable and understanding of the process and how to make it a pleasurable experience. We weren’t looking to purchase a car that day, but Chris really listened to our wants and needs and was able to find something for us that fit what we were looking for. He was very patient with us as we made our decision. Hands down the best experience I’ve had buying a car.

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

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

This is really a great place, they are so busy it is amazing. Pricing on some cars are fantastic. I just sent a friend there to look at one and it was gone by the time she arrived. I'm sure she'll find another. We bought an SUV, but I am also in the market for a sedan! This will for sure be my Go To place!

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

We would like to give a shout out to Hannah Kane on helping us purchase our Mercedes Benz. Hannah was a great sales person. Our purchase was a great experience.

Was a great visit. All as planned. Fast, communication from Dean was great. Could not be happier with the warranty repair and the smooth process to get it completed.

Ok when I tell you my salesperson Ronnie Robles is the best he literally was very patient and helpful with me he pulled my up 3 cars when it was literally time for him to get off and leave he didn’t put me out he didn’t get angry he was just patient until I finally picked the car I wanted mind you this was Saturday and today i finally picked my new baby up and I’m in love with it thanks Ronnie and the whole Hoffman Estates family everyone was so helpful and nice no mean attitudes I got from anyone also to my girl Claudia she was the bomb she help me register my car to my phone and she also went over ever feature I needed to know about my car with me she took my pictures and she knew how a girl loves her pictures lol thanks Claudia everyone was just so patient you guys rock

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.

They contacted me immediately and explained their process for vehicle delivery. Unfortunately I couldn’t find a suitable vehicle. Very professional and courteous.

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.

Tony's customer service is excellent. He is very knowledgeable and informative. We highly recommend anyone in the market and will be referring our friends and family to him. We could not have asked for a better experience.

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.

Bruce Jones is the best worker of the center, he helped us to pick and get a car, he has a lot of patience. Thank you, Bruce!

Had my Mercedes Sprinter RV serviced here. I have used them in the past and it is always a great experience. Mark in service provides great customer service keeping me informed on what is going on during my appointment. They always go above and beyond. Their quotes are on point and I never feel like they are trying to take advantage of me. One of the best dealerships I have ever worked with.
