Used Mercedes-Benz GLS 450 for sale near Wheaton, IL under $899,990

I’m really impressed with the service at Autos of Chicago. The staff was knowledgeable, friendly, and took the time to understand what I needed. They walked me through each step and made sure I felt confident with my decision. My used car runs perfectly. I would definitely return and recommend this dealership to anyone.

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.

Staff were all kind helpful and very professional The staff allowed me time to look at a car. Price was very competitive

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 had a great experience at Autos of Chicago. The team treated me with respect and made the entire process simple. They were honest about the car’s condition and offered a fair price. My vehicle runs perfectly, and I appreciate their professionalism. I would definitely come back and recommend them to anyone looking for a used 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.

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

Salesman was not pushy. Very helpful. There were a few cosmetic issues with the vehicle, but they had just gotten it in and out did not concern me. The appearance of the dealership is very basic, but I think that is part of the reason they don't have a ton of fees. They were very transparent about everything.

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.

Awesome experience came in looking a Ford Explorer financing was tuff but we got it done quick and easy honest people

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.

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.

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..

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.

Happy to purchase from this dealership rather than others in town! Turned out to be much better deal and car. Thank you

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!

This is one of the best Mercedes dealerships if not the best in the Midwest region. They ALWAYS do a professional job and take good care of me

Had a great experience ordering the Cadillac Lyriq thru Heritage Cadillac. From start to finish it was a pleasure dealing with Elizabeth and Isaac. They did all the work.. I highly recommend Heritage Cadillac and I looing forward to getting this awesome Cadillac. Thank you.

Great service very good with communication and very fast with the paperwork Vehicle vehicles are clean and beautiful and great options to pick from. Harris was the one that took care of me with the process. He is great to work with.

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.

Chris Antzaras at Ultimo Motors has represented my family for 2 car purchases at Ultimo Motors East. He made the purchase of my Corvette Z06 so easy. He is professional, knowledgeable and easy to work with. I understood everything. He’s honest too. I will never purchase from another agent. What a great experience!

Noman was fantastic! Found a Mercedes online and called BG motorcars. They were very helpful, sent me the Carfax and extra pictures. Hassle free and nice experience. I highly recommend them.

I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV

Julio R and Gary K did what was necessary to get my car repaired in a short time with care and respect.

Jamie was great to work We had a less than great experience at a different Mercedes dealership after contacting Hoffman Estates he stepped up and found us the vehicle that we wanted and had it at the dealership in less than a week The rest of the team was just as great as well They made purchasing our first Mercedes the awesome experience it should be Thanks again to everyone at Hoffman Estates especially Jamie We will definitely return Thanks again Darin and Kay
