Used Mercedes-Benz GLS 450 for sale near Peotone, IL

We drove an hour to this location specifically for a recall service. We were not satisfied with a local dealerships service department. From the moment to pulling the car in the shop to the end of being complete, the service we received was very pleasant. The Service Advisor , Jim DeVault is very personable and professional & very happy to all address our concerns and request. The waiting room was a plus! The 1 and only thing I would suggest to be honest is keep the television on a neutral program. ( We agreed with a few other waiting customers , we'd rather watch a cartoon ;)) We will be back for any of cars needs. Thank you !!!!

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.

Mr, Money Carlos was absolutely fantastic! He was very knowledgeable and helpful in assisting me with purchasing my brand new 2026 Chevy Equinox. Very satisfied customer

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.

Great experience easy and nice to deal with Jason got me some great financing with a credit union

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 have inquired about a 2011 BMW 535 that was for sale. One of the salesmen did a full walk around video with additional photos and provided it prior to us goin in and looking at the vehicle. Great customer service, I would recommend this dealership to anyone looking for honesty and full transparency on a vehicle they are looking about to purchase from Unique Luxury Motors!

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.

Our representative, Jordan Usher, was professional and kept true to his word... it was a straightforward deal without any games. We will certainly return in the future when we are ready to buy again.

I have test drive the range rover the X7 and I find this is the best for me , it has the room and comfort plus all the safety plenty of power too with a good mileage for a car this size .

Excellent communication. Prices very good. Transaction quick and accurate. Excellent customer service. Polite and courteous. Great selection of vehicles, especially Teslas.

We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Super impressed and happy with my 2024 BMW M3 Competition I purchased at Baha’s. The car’s beautiful, rate was awesome, and the whole experience was wonderful

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 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

Great team to work with, and very friendly very quick service. Great selection of cars too. Will definitely refer them to my friends. Very nice place

The Mercedes GLS is my second Mercedes and like always very satisfactory process to buy at the dealer. Great vehicle! Outstanding engine and transmission! Very confortable for the entire family 😂

Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.

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.

⭐⭐⭐☆☆ (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.

Marty Lucas did a fantastic job. He is very professional and friendly and has a ton of product knowledge. I would highly recommend seeing Marty if you are looking to buy a vehicle. Tony Griffith handled the financing and was also wonderful to work with. The whole experience was great and another highlight is we didn't have to deal with them having added packages on the vehicles.

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

Alex was great to work with. He communicated well and kept me in the loop during every part of the process. I'm now waiting for my vehicle to be shipped

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.

Love the new experience. It’s top tier. Blew me away with the customer service!!! I recommend this place.

Great service got the car we wanted, will be recommending to Al my friends and family.

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.

The service went well everybody was good enjoyed my visit Service rep called when the vehicle was ready and was ready on time Wedding room was he quit with coffee tea rolls etc comfortable chairs

Keeping this short and sweet. I call Adam Auto to On Saturday 11/11/2023 I called Adam Auto Group of Crestwood, Il to inquire about a vehicle. The salesman James answered all of my questions. It's hard to get a salesman to answer questions over the phone they all usually want you to come in right away. He did not pressure me in any way to come in. After a few minutes he called me back and gave me more details about the car, it was close to closing but he convinced me to come in to see the vehicle for myself. When I arrived he took me out to see the car and it was everything he said it was and had every amenity I was looking for my new car to have. He was very polite, professional and knowledgeable about the vehicle. His professionalism and patience with me was what I enjoyed most. Before I left I put down a deposit to hold the vehicle. Today 11/13/2023 I went back and got my car! Please ask for James if you decide to visit Adam Auto Group he will not disappoint!

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.

Let start off my saying these bugs are great. Made sure I was comfortable with what I was buying and made the process very easy and simple.

High Line Auto Sales is hands down the best used vehicle dealership in the area. Their expertise and care really reflect when it comes to the vehicle they sell. I never hesitate to recommend them to an acquaintance, friend, or family member because I know they only sell amazing quality vehicles.

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.

I had been searching for months to find the right A8L. I had been to another dealer to look at a 4.0 in the color I wanted, but there were so bad it almost turned me away from Audi altogether. I saw on cars.com they had a car that was very close to my requirements and it was one year newer and Audi Certified. I did not get as much for my trade as I reasonably expected but overall I feel like I got a good car at a good deal. Wendy was my "brand specialist" and was very professional and knowledgeable. I recommend them as it was a good experience, which I can not often say about buying a used car at a dealership.
