Used Mercedes-Benz GLS 450 SUVs for sale near Olympia Fields, IL

I was very impressed with the professionalism at this dealership. Very clear and straight forward, they had no hidden fees. I came from another dealership that tried to sell us no optional "Premium Package" for $1000 that did nothing. These guys are great and would check them out if you're in a market for a used car, thanks Gyt!

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!

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

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.

I contacted them and had a quick response. I was able to test drive the car that night. Everyone there was extremely courteous and able to answer any questions. I ended up buying the car that night. No pressure, no gimmicks, just honest and pleasant. I highly recommend working with these folks, they put the customer first! Thank you, Simon.

Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

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.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

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!

I didn’t end up buying the car because i didn’t make my decision fast enough. It was sold. But the service was consistent and precise with emails and speedy quick at responding. Loved the service and would definitely recommend this dealer.

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

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.

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.

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

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.

Great inventory, pricing and good service but service is high price for somethings like oil change, other mercedes dealers $100 less for identical service. Walter, salesperson, easy to work with.

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.

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.

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.

Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.

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

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

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.

I had been searching for months to find the right A8L. I had been to another dealer to look at a 4.0 in the color I wanted, but there were so bad it almost turned me away from Audi altogether. I saw on cars.com they had a car that was very close to my requirements and it was one year newer and Audi Certified. I did not get as much for my trade as I reasonably expected but overall I feel like I got a good car at a good deal. Wendy was my "brand specialist" and was very professional and knowledgeable. I recommend them as it was a good experience, which I can not often say about buying a used car at a dealership.

The staff was efficient and my car is running smoothly. My vehicle was covered under warranty but it was difficult to work out due to it being a weekend. The staff was very helpful with getting back to me and keeping me updated through the next week and were able to fit me in right after.

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.

Good service good attention nice place to visit. I will add just one thing at the service shop, a bilingual employee thanks.
