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

Had an absolutely wonderful experience at South Shore. They love their clients and the customer experience is unmatched. Best experience I've ever had in a dealership!

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.

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.

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..

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!

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

Friendly and professional service rep, work completed as promised, vehicle returned washed. Nice waiting area.

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.

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.

Great service very welcoming beautiful dealership, staff very friendly and helpful, cars and price are on point. Thank you Autos of Chicago I will be back!

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

I recently had the pleasure of working with Chris when purchasing my new vehicle, and I couldn’t be more satisfied with the experience

Excellent Cust service!! Yassin was phenomenal and made sure that all of our concerns were addressed and taken care of.

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

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.

Thanks Dennis and Team for all your work with me picking up a classic car! Can't wait for it to arrive!

This car was very comfortable there was plenty of leg room and I really enjoyed the smooth ride and space for all the grands and their friends

As a return customer with Mercedes-Benz of Hoffman Estates, I am very satisfied with the customer service throughout the dealership. Worked with David Bennett on my trade-in and his expertise helped me to understand and narrow down my vehicle choice. The entire Team was a pleasure to work with and they got me out the door quickly with my new GLE.

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.

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!

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.

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

Just wanted to mention that I had a great experience buying my F-Pace from Patrick Jaguar of Naperville. Dale was just fantastic and went above and beyond helping me during the the whole buying process. The rest of the team (Finance & GM) was also excellent in their interactions with me. I initially chose Patrick Jaguar because they were one of only 2 Jaguar dealerships in the area that were not marking up their vehicles over MSRP, specially the hard to get ones like the F-Pace SVR which I bought. I've only needed to use their service department for a minor cosmetic issue that was sorted out in one day. Great job all around.

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.

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.

We bought a Fusion 2016 and had a few things wrong that Mark fixed with no problem the next day Thanks for the great service and price!!! Bob Valiska

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.
