Used Mercedes-Benz GLS 450 for sale near Forest Park, IL under $750,000

I had a fantastic experience at Honda on Grand. The staff was knowledgeable and friendly, and their selection of vehicles was impressive. I never felt pressured to make a purchase, and the whole process was seamless from start to finish. I would highly recommend Honda on Grand to anyone in the market for a new car.

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.

Service was amazing! I would say we were in and out within an hour and a half our advisor explained everything to us. We have no complaints.

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.

Fast and easy. All staff was pleasant, well spoken and mannered. Made an out of state purchase with a few email and phone calls. Sales person Luke was excellent.

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

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.

Easy buying experience. They were very professional and the whole purchasing process was with one person.

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!

I had an outstanding experience at Mercedes-Benz Naperville working with Abraham during my recent vehicle purchase for my wife. From the very beginning, he exceeded my expectations in every way. Abraham was incredibly attentive, really listening to what I was looking for and helping me find the perfect vehicle without any pressure. His knowledge of the Mercedes-Benz lineup was impressive - he explained all the features clearly and made sure I felt completely comfortable with my decision. What truly stood out was his follow-up after the sale. Abraham checked in to ensure everything was going well and even went out of his way to resolve a minor issue I noticed after taking the car home. That level of dedication is rare and truly appreciated. I would highly recommend Abraham to any friend or family member in the market for a car. His professionalism, expertise, and genuine care made this transaction a great car-buying experience.

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.

Great experience with John and Florin. They know their stuff which made this transaction stress free.

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

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.

Absolutely great dealership to work with, esp with Arsh and Milan. They were able to help me get what I was looking for. Very detailed and kept me up to date on the progress. Will definitely work with them again. Thank you EMC!

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.

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.

I just bought a 2019 Mercedes-Benz CLS 53 AMG from Chicago Auto Place. I'm out of state but deal was great. Took about 5 days to get delivered. Longer than i wanted but they delivered. Kept communications the entire time. Ricky was great. In the process i got worried and started researching. There are some people years ago that didn't review well. I really don't thinknthe deserve those reviews. After i got the car i asked the owner about them. He said they changed their business modelnto higher end cars with lower miles. And it has worked for them. I am 100% happy and have a stellar car. Inwould recommended whole-heartedly. They are in Chicago and i amnin Texas. Stressful buying online but they delivered on all cylinders.

Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

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.

I just purchased a Infiniti QX 60 from Motor Werks in Barrington, IL. This will be my third purchase from this dealership and my second experience with Mark Smith my salesman. Mark Smith and Lorena Mena the sales manager make car purchasing a enjoyable experience. No pressure whatsoever and after negotiating a fair deal I drove home in my new car. You would be extremely hard pressed to find a more reputable and honest dealer. No hidden fees and the whole process was completed in about an hour. If you are looking for a new or used Infinti let Mark help you with your search. Tell Mark that Kevin sent you!

Very Profesional and helpful seller Paul Sidorski !! Working with Paul was such a great experience. Highly recommend dealerships Mercedes Benz of St Charles to anyone looking to buy a car

Amazing experience. Made the process so simple for me to get what I want. Would definitely recommend to everyone

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.

I recently had the pleasure of working with Exclusive Autohaus, and I can confidently say that they provide an outstanding experience from start to finish. From the moment I walked in, the staff was incredibly friendly and professional. They made me feel welcome and took the time to understand my needs and preferences. About four months ago, I purchased a 2014 Audi R8 from them, and I couldn’t be happier with my decision. The car is in pristine condition, and it’s clear that Exclusive Autohaus takes great care in selecting and maintaining their vehicles. The entire process was smooth and transparent, and I never felt pressured, which is a huge plus when buying a car. What really stood out was the level of customer service. They went above and beyond to ensure I was satisfied, answering all my questions and offering helpful advice. The team at Exclusive Autohaus is knowledgeable and truly cares about providing an exceptional experience. If you’re in the market for a vehicle and want excellent service, a great selection, and a no-hassle process, I highly recommend checking them out. I’ll definitely be returning for any future car purchases!

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

We purchased a 2024 Corvette spur of the moment. (No regrets!) From the moment I walked in, I was immediately taken care of. Kim was amazing from start to finish- she was sweet / funny! The process did not take as along as we would at any other dealer. I would definitely be coming back for any other purchases we may need in the future!

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

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.
