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

Agent Keith greeted me when I pulled in for service.
Agent Keith greeted me when I pulled in for service. He asked me to step inside and would be there in a minute after checking my VIN and mileage. He helped me locate my rewards number on my phone and went over the prices for my oil change, tire rotation and new battery. Later when I was in the waiting area, Keith informed me that 30,000 mile maintenance needed attention. I agreed to the two services recommended and was still out of the dealership in around two and a half hours. Keith processed my 10% discount and informed me of a $20 rebate for the new battery. He explained the process for requesting the rebate online. I highly recommend Garber Chevy for their sales and service. I have bought three cars here and am willing to drive the seven miles to Garber even though there are Chevy dealers in Lansing, Ill where I live that I no longer deal with if possible. The other dealership will always ask me three to four times if I would like to trade my car in or do I want to look at new car models. I don't like that, if I want to look at a car or want a trade-in, I'll ask. Go see Garber and you will be surprised!
Love it so far
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 stopped into Mercedes of Westmont as a second stop in
We stopped into Mercedes of Westmont as a second stop in our search for a new car. I am not really a fan of buying new cars, we typically buy a car and drive it until it’s dead, just so we don’t have to go thru the whole purchasing process of getting a new car. Chris at Mercedes of Westmont has completely changed my outlook on buying new cars! He is very professional, but yet relatable and understanding of the process and how to make it a pleasurable experience. We weren’t looking to purchase a car that day, but Chris really listened to our wants and needs and was able to find something for us that fit what we were looking for. He was very patient with us as we made our decision. Hands down the best experience I’ve had buying a car.
I’ve had many Mercedes-Benz models over the years,
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..

Perfect for the family of 6 like me.😍😍😍
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.

Marty Lucas did a fantastic job.
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.
Best SUV we've ever owned.
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

Nice man pick up from train station i love my new car A++ fixed my AC too and I left happy
Large yet stylish enough to carpool the Grands
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/

⭐⭐⭐☆☆ (3/5 Stars) I had a great initial experience with
⭐⭐⭐☆☆ (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.
I bought this vehicle is a retirement car.
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.

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!
Great SUV
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.

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.

3 month review
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

This is the third S-class Mercedes I have purchased from
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.

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!

Super happy with my experience. Drove right off the lot with my new car and no complaints. Have nothing but great words for these guys and definitely zero complains. Check them out for you next car buying experience. Made it all way way back to Des Moines.
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.
