Used Mercedes-Benz GLS 450 for sale near Richton Park, IL

Our representative, Jordan Usher, was professional and kept true to his word... it was a straightforward deal without any games. We will certainly return in the future when we are ready to buy again.

This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

Alex was great to work with. He communicated well and kept me in the loop during every part of the process. I'm now waiting for my vehicle to be shipped

The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Love the new experience. It’s top tier. Blew me away with the customer service!!! I recommend this place.

My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

I bought a new Honda from a dealer closer to my home- had a horrible experience back in 2015. I decided to drive for service to Honda Superstore in Lisle, and wished I had bought my Honda initially from them. Service is top notch. They care about the cars and the people that drive them. Flash to today. I’m in the market for a new car- a Honda. I drove the extra 5 miles- to Honda Superstore in Lisle- and was greeted by a kind- knowledgeable Salesmen named Brad Brost, and also met the Sales Mgr. Brent Reeves. They listened to my concerns- and treated me- a single woman walking in the door- with the compassion and respect as a consumer- I deserve. I’m walking away today with the perfect car for me. Keeping my selection in the Honda family- and staying loyal to this dealership- makes me have pride in not only my new car investment- but the lic. Plate that bears the name- Honda Superstore of Lisle. Thank you Brad Brost and Brent Reeves.

Great service got the car we wanted, will be recommending to Al my friends and family.

Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

The service went well everybody was good enjoyed my visit Service rep called when the vehicle was ready and was ready on time Wedding room was he quit with coffee tea rolls etc comfortable chairs

I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

Felt welcome as I entered the door. Staff was available and when I asked for the sales person that I had been communicating with, salesperson was waiting.

The interior was very comfortable and the color combination made the experience very nice , was very surprised by the power that came from the engine

Keeping this short and sweet. I call Adam Auto to On Saturday 11/11/2023 I called Adam Auto Group of Crestwood, Il to inquire about a vehicle. The salesman James answered all of my questions. It's hard to get a salesman to answer questions over the phone they all usually want you to come in right away. He did not pressure me in any way to come in. After a few minutes he called me back and gave me more details about the car, it was close to closing but he convinced me to come in to see the vehicle for myself. When I arrived he took me out to see the car and it was everything he said it was and had every amenity I was looking for my new car to have. He was very polite, professional and knowledgeable about the vehicle. His professionalism and patience with me was what I enjoyed most. Before I left I put down a deposit to hold the vehicle. Today 11/13/2023 I went back and got my car! Please ask for James if you decide to visit Adam Auto Group he will not disappoint!

I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

Let start off my saying these bugs are great. Made sure I was comfortable with what I was buying and made the process very easy and simple.

I have purchased 5 cars from Ultimo Motors East. All of the transactions were smooth, fast and hassle-free.

Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

Excellent communication. Prices very good. Transaction quick and accurate. Excellent customer service. Polite and courteous. Great selection of vehicles, especially Teslas.

I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

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.

Happy that I purchased at this dealership rather than others in town. Turned out to be better deal and better car!

Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

We just bought a high mileage TESLA from star motors. The entire experience and the car itself was great. Alex can actions as very reliable, open and ready to help always. Payment and shipping were managed in a very honest and trustworthy manner.

I have test drive the range rover the X7 and I find this is the best for me , it has the room and comfort plus all the safety plenty of power too with a good mileage for a car this size .

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.

From the moments I got in the dealership until I left I was treated very nice and very welcomed. I looked at Lexus RX and end up buying it because I felt comfortable and car is clean with good competitive price. Very recommend

We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Great service and easy to work with. In and out quickly and they had a great selection of imports.

Well designed and plenty of room in the 3rd row. leather is rich, feels nice and comfortable to sit in . Plenty of power, Sharp and clean lines

It was a great experience, Will was very nice and well inform as to what was need for my break pads

Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

Just purchased a Porsche Cayenne Hybrid, and the experience was fantastic! Simon was knowledgeable, professional, and made the process seamless. The car is a perfect blend of power and efficiency—exceeded my expectations. Highly recommend Simon for anyone looking for a Porsche! 🚘🔋 JD
