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

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.

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.

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.

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 purchase a 2019 Qx60 my experience was very very good sale person Thomas pates did a wonderful job to get me in this car everyone was helpful I will purchase another vehicle from there I am from Milwaukee thanks carwise

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.

Thank you very much for Greorge Adam who help me with my car .George is very profesional and very helpful .Great job!!!

Yesterday I purchased a car by phone for the first time. As a senior citizen I sold my car on the 9th of March thinking I would get totally travel by taxi or Uber or Lyft but I under estimated the value of getting up and going when you like. The team at CarMax from beginning to directions to the highway were the very best. Each and every member made me feel valued as a customer. And feel like they were treating me like they would their family members. You could not ask for more than that. Bj

My experience at Autos of Chicago was truly impressive. The team was professional, patient, and never made me feel rushed or pressured. They walked me through the features of each vehicle and helped me choose one that matched my expectations. The pricing was fair, and the paperwork process was quick and organized. I left feeling confident and happy with my purchase. This dealership is a great choice for anyone looking for quality used cars and excellent customer care.

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.

Excellent no xx dealership! No hidden fees or stress! Transparent pricing and a great deal for exactly the car I've been dying for. Would absolutely buy from them again.

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.

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

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.

This was the best experience we’ve ever had in buying a car. Would recommend Mercedes Benz of Barrington. They were more than accommodating.

John along with his team and MW Infiniti were great to work with. John was very knowledgeable and made the process and my decision any easy one to make.

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!

Omar, Eric and Tony were awesome to work with!! I came from to look at the Mercedes and it was my first big car purchase. I always drove Honda but wanted something more luxury. I noticed online ENE Motors had a big selection of luxury cars and imports so if I wanted to upgrade to another Honda Pilot they had one. Well after I told them what I was looking for they had me drive one of the 2018 Mercedes-Benz GLS 550 they had, during the test drive I knew that I wanted it. When I got back they started they had already appraised my trade and we went into the office to get financing. I was very happy with the rate and terms. They made sure everything went smooth and did everything so I could take care of purchase and trade in all in one trip. Thanks guys...I love my Mercedes GLS!!!

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 bought a car from this dealership and had a fantastic experience. The staff was knowledgeable, friendly, and made the whole process smooth from start to finish. They had a great selection of vehicles at competitive prices. Highly recommend to anyone looking for a reliable car and honest service! Thanks Sammy

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.

We are out of state, repeat buyers who just bout our FIFTH car from EMC. Great experience every time we are in the market for a car. Arshad and team top notch! Thanks EMC!

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

Very professional and helpful. Also, the salesperson was very helpful and accommodating. I'm happy to recommend!

Prompt and courteous reply to my inquiries. Remained in contact but not pushy... good balance. Good 'dealer-sense' and manners.

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

The salesperson was very on with the auto I looked at but we couldn’t come together about the price

Owned this suv for 15 months purchased certified preowned with 33k miles and about half the price of new. The truck has only two issues to note but otherwise rides, drives and in all other respects is far and away the best automobile I’ve owned - which saying a lot for an old guy. The standard tires are nearly useless in snow and ice and we hope an aftermarket replacement will address the issue later this fall. The more annoying downfall is that although the ride is otherwise amazing, the truck handles sharp bumps very poorly - almost the feeling of a car with workout struts. I have had the struts replaced under extended warranty but the improvement was marginal. For most drivers the suspension issue wouldn’t likely be as much an annoyance but for my fellow ocders, be warned. I would buy the truck again, however.

I just got my Tesla at Affinity. Milton was amazing. He knew exactly what I needed. I strongly suggest that you go see him before EV credit is over.

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

I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

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.

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.
