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

great selection of cars... Adam has great knowledge. very happy with my tesla. i would buy from them again

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.

I liked pretty much everything. I negotiated the price over the phone and started the financial lease application remotely to save my time at the dealership. When I arrived - they were waiting for me, the car was ready, all the paperwork went seamlessly and fast enough for the procedure of exchanging my previous leased car with the new one. My sales representative was very courteous and attentive. Actually, everyone at the dealership with whom I communicated was above and beyond any expectation. After 30 years of purchasing cars I can say that this was my best experience so far.

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 had a great experience working with Noman. He was informative, no pressure, easy to work with, and negotiated fairly. We found a quality used car. After a test drive we had a mechanic check. Along with the Carfax report Noman provided (we also ran our own report which matched), we were confident we knew what we were buying. Plus Noman delivered the car to my home. The car is great! We are very happy. We did shop a few other places and this was the absolute best! Thank you Noman for your good service and am thankful we got a great car!

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.

My oil change was less expensive than my estimate that I received when I arrived. Nick, my service advisor, did a great job and got me back on the road in less time than expected.

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..

We recently purchased a 2025 C300 4Matic from Romeoville MB, and the experience was outstanding from start to finish. Jayda and the entire staff were incredibly courteous, knowledgeable, and helpful throughout the process. They made everything smooth and stress-free. Highly recommend Romeoville MB for anyone looking for a Mercedes-Benz vehicle and top-tier customer service!

Great service! I felt welcomed and at ease. The staff were very friendly and I didn’t feel pressured to buy!

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
