Used Mercedes-Benz GLS 450 for sale near Sauk Village, IL

My service advisor was Joe. He did such an excellent job with assisting me from start to finish. Let me know everything that was going on every step of the way with my vehicle. He made all the proper recommendations, got my car back up and running very quickly.

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.

I didn’t end up buying the car because i didn’t make my decision fast enough. It was sold. But the service was consistent and precise with emails and speedy quick at responding. Loved the service and would definitely recommend this dealer.

I contacted them and had a quick response. I was able to test drive the car that night. Everyone there was extremely courteous and able to answer any questions. I ended up buying the car that night. No pressure, no gimmicks, just honest and pleasant. I highly recommend working with these folks, they put the customer first! Thank you, Simon.

Great Used Car Purchase Jacob Rocks! Bought 21 Tacoma from them. Had the best price in country for my truck. Jacob the sales guy and Rob in finance got me the best rate pretty much a new car rate on a used truck. I didn’t buy a warranty because of the fact that Toyotas don’t need one but the price on the warranty was crazy inexpensive. I’ve bought well over 100 cars and trucks in my life… never have I said yes to a dealers number I am king LowBall… I said yes to their price great trade value great price on truck and great rates. Thanks guys!

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.

John Pewitte is the man to go to! Great service and he helped me find the perfect car for me and my family!

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.

Jason did amazing Job I can’t believe the deal I got thank you so much Luxury AutoMaxx I came for. GMC and left with a Honda Odyssey for my family I’m so has happy

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 purchased a vehicle out of state sigh un seen from Unique Luxury Motors. These guys provided us detailed photos, walk around video and even a driving video within 15 minutes our request. Finalized the deal the same day and within 2 days we had the car shipped to our door! Wow what a customer service and transparency that these guys provide to their customers! We are more than happy with our new BMW, thank you Unique Luxury Motors keep up the good work!

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.

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.

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 .

⭐⭐⭐☆☆ (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.

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/

We bought our 2021 Tesla Y from Adam. If there is a way to put you in your dream car he will find it. Awesome guy to work with. Thanks again Adam!

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.

Wonderful atmosphere, they have everything from Luxury, sport, and reliable. I’ve been doing business with Baha Auto for a years now. Service is always excellent!

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 bunch of guys. Great to deal with. Great inventory. Wonderful place. Very knowledgeable. Great selection. Bought a very clean Range Rover Be back again.

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 😂

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 have bought a lot vehicles in my life but this was one of the best experiences I’ve ever had the entire staff was great

5 stars for Bill Jacob's! He was very friendly, courteous, and helpful with the service of my Land Rover. I definitely recommend Jacob's Land Rover dealership!

Great inventory, pricing and good service but service is high price for somethings like oil change, other mercedes dealers $100 less for identical service. Walter, salesperson, easy to work with.

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 wanted to get a car fairly quickly and knew what I was willing to spend. My salesperson Paolo was extremely helpful and found me my car in the color I wanted in less than a week. To my surprise, the package I purchased even came with several bonus accessories for protecting the interior. Paolo took his time with me and explained every feature in the car (even after closing), which was amazing since the manual looks like an encyclopedia. The dealership followed up later with a Zoom call to answer any additional questions I still had and they’re sending me a free gift! Overall, I would absolutely shop here again and recommend this dealership to my friends!

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
