New and used 2025 Mercedes-Benz GLS 450 for sale near Plainfield, IL

Michael, my sales specialist, was amazing. He was knowledgeable, helpful, kind and most importantly, not pushy. I was test driving many cars in different places and he was very patient with me. In the end I purchased my CLA250 and I couldn?t be happier!

Liz in sales was always helpful and made the buying process a breeze. She addressed all my concerns about the Carfax report, pricing & extra keys. The dealership's facilities are convenient & very clean. The vehicle itself was in great condition. The financing process can be made more transparent. It would be helpful to know about the extended warranty options beforehand as cost of these options can add 10-20% to the cost of the car. It is hard to make this decision at the last moment. However, I could have added to the financing.

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.

Absolutely amazing service. Everyone was friendly, professional, and made the whole process smooth and easy. The work was done quickly and with care, top tier all around. I’ll definitely be coming back for future service needs.

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

Wonderful experience from first contact through sale. Albert Tulo was knowledgeable, friendly, and efficient with processing my used car sale! Highly recommend!

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.

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.

Everyone at every level of the organization - be it sales, finance or service - were extremely professional with a top concern for customer service. We really appreciated this above all else.

Mercedes Benz and honestly it was the most stress free car buying experience I’ve ever had. Kimberly Quintero, in sales, was extremely patient and straight forward. She dealt with me sizing the back seats and taking calls with my wife regarding child car seats and positioning. Kimberly was the absolute best when it came to showing the vehicle and even doing research on work done by the prior owner. It was also a breath of fresh air to deal with someone who was so transparent and not aggressive at all. When it came to signing paperwork Fay Demos shocked me, she was able to beat my credit unions rate. Went in under the impression I was going through my credit union, and nope she beat it. Both Kimberly and Fay went above and beyond and definitely earned my business. I would highly recommend anyone shopping for a Mercedes, or used vehicle, to buy through them.

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.

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.

Very Profesional and helpful seller Paul Sidorski !! Working with Paul was such a great experience. Highly recommend dealerships Mercedes Benz of St Charles to anyone looking to buy a car

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.

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.
