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

Made me feel like family as soon as I walked in very helpful and accommodating to my needs didn?t feel rushed at all great staff and location overall.

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.

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.

It was professional and satisfying. Staff was friendly and accommodating to my schedule. They kept me updated to frequent updates on status, explained all features of the car.

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.

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

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.

The dealership contacted me and followed through on everything I asked and needed of them. Great overall 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..

AMAZED! 5 Stars! I’ve been car shopping off and on for 6 months, I’ve watched hours of car reviews on you tube and talked to tons of owners on Facebook groups, test drove new and used, sedans, crossovers and finally Outback’s. I was close to buying about 4 different vehicles over the last 3 months but the sales people and finance managers soured my taste for even wanting to buy anything from a dealership. I was able to get a email quote and set up a time to test drive the different trims with Gabriel Talpos. He was with a customer when I arrived and with in a minuet I was asked if I needed help unlike some dealers. Jeff Schade showed me all about the Outback’s and patiently answered all my questions and we even got to experience some Subaru like down pours. It was close to closing so I came back Saturday to try the Wilderness and it checked all the boxes, plus for me it had the most amazing acceleration of all the outback trims. Jeff was super patient and not pushy at all, the managers made a great offer that I didn’t even have to bargain for. The last part Finance managers.. always so scary. I worked with Chris Thomas, he was super pleasant! Quick and not pushy either, very friendly. I’ve never ever had a finance manager expierence that didn’t leave me with dread and being pushed around, so it was refreshing! Everyone I met at Grand Subaru was friendly and I can’t say enough about how different this dealership is for the better. I recommend you give them a shot and test drive some Subarus, they definitely don’t get the attention they should!

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.

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

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

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

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!

Great customer service and Bob was helpful but not pushy at all during the process. Great experience that was worth the lengthy drive. I would recommend!

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

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!

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

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!

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

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.

⭐⭐⭐☆☆ (3/5 Stars) I had a great initial experience with Highline Autos. The transaction was fast, smooth, and professionally handled. The team—especially Zuhair, the owner, and the young Ghalib—was responsive and knowledgeable, making the buying process straightforward and low-stress. Their professionalism and business reliability stood out during the deal. However, about a week later, I was disappointed to discover that the tires on the car I purchased were leaking. Upon inspection, it turned out that plugs had been used as a temporary fix rather than properly addressing the issue. This was unexpected and concerning, as I had hoped for greater transparency regarding the vehicle's condition. While I appreciated the efficiency and service during the sale, I hope the team takes this feedback seriously and ensures that future vehicles are fully inspected and represented. I’d encourage potential buyers to have a thorough inspection before finalizing a purchase.

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 haven’t purchased here, but I’ve been a prospect and they are well priced and very transparent with the vehicle history. They’re also prompt with follow up. The person who posted the fact that they are Ukraine owned has zero impact on them as a business. In fact, the same person posted twice just to damage the ratings. There’s always a dingdong out there.

Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

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.

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

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.

Good for Travel and Towing, very convenience for every needs. It has most of latest technologies installed inside the car. Many advanced options require users to read the manual.
