New and used 2025 Mercedes-Benz GLS 450 SUVs for sale near Oswego, IL

Liz in sales was always helpful and made the buying process a breeze. She addressed all my concerns about the Carfax report, pricing & extra keys. The dealership's facilities are convenient & very clean. The vehicle itself was in great condition. The financing process can be made more transparent. It would be helpful to know about the extended warranty options beforehand as cost of these options can add 10-20% to the cost of the car. It is hard to make this decision at the last moment. However, I could have added to the financing.

Maintenance team technician it’s very professional they provide excellent service thanks to Rob at service

Very kind and caring . Helped alot to make the deal. Salesman was kept me informed. Lending Maneger also put extra effort to make the deal.

Michael, my sales specialist, was amazing. He was knowledgeable, helpful, kind and most importantly, not pushy. I was test driving many cars in different places and he was very patient with me. In the end I purchased my CLA250 and I couldn?t be happier!

Wonderful experience from first contact through sale. Albert Tulo was knowledgeable, friendly, and efficient with processing my used car sale! Highly recommend!

The loaner is a very convenient option during the timely completion of the new brakes and a repair. We feel very confident using the Service Dept at this location.

I just bought a one year old GLE 53 Coupe from michael Moran and had a great experience. He was a real professional, none of the typical car dealer nonsense. Everything was very easy and they delivered the car to me one day later. Very good experience

Absolutely amazing service. Everyone was friendly, professional, and made the whole process smooth and easy. The work was done quickly and with care, top tier all around. I’ll definitely be coming back for future service needs.

Everyone at every level of the organization - be it sales, finance or service - were extremely professional with a top concern for customer service. We really appreciated this above all else.

They have discount price cars in their website less than the market price and they drove my car like 2 hours and delivered me. Super friendly. I highly recommend.

Motorwerks in General goes the extra mile of offering services and support for all of your luxury car purchases. We love Motorwerks!!

Great experience as soon as I walk in every one was friendly and helpful. I recommend this dealership 100%

Great service as always. Really liked Francisco. He was very personable and extremely helpful. Very easy to work with. And that's all I have to say.

I had an outstanding experience at Mercedes-Benz Naperville working with Abraham during my recent vehicle purchase for my wife. From the very beginning, he exceeded my expectations in every way. Abraham was incredibly attentive, really listening to what I was looking for and helping me find the perfect vehicle without any pressure. His knowledge of the Mercedes-Benz lineup was impressive - he explained all the features clearly and made sure I felt completely comfortable with my decision. What truly stood out was his follow-up after the sale. Abraham checked in to ensure everything was going well and even went out of his way to resolve a minor issue I noticed after taking the car home. That level of dedication is rare and truly appreciated. I would highly recommend Abraham to any friend or family member in the market for a car. His professionalism, expertise, and genuine care made this transaction a great car-buying experience.

Ok when I tell you my salesperson Ronnie Robles is the best he literally was very patient and helpful with me he pulled my up 3 cars when it was literally time for him to get off and leave he didn’t put me out he didn’t get angry he was just patient until I finally picked the car I wanted mind you this was Saturday and today i finally picked my new baby up and I’m in love with it thanks Ronnie and the whole Hoffman Estates family everyone was so helpful and nice no mean attitudes I got from anyone also to my girl Claudia she was the bomb she help me register my car to my phone and she also went over ever feature I needed to know about my car with me she took my pictures and she knew how a girl loves her pictures lol thanks Claudia everyone was just so patient you guys rock

Mercedes Benz and honestly it was the most stress free car buying experience I’ve ever had. Kimberly Quintero, in sales, was extremely patient and straight forward. She dealt with me sizing the back seats and taking calls with my wife regarding child car seats and positioning. Kimberly was the absolute best when it came to showing the vehicle and even doing research on work done by the prior owner. It was also a breath of fresh air to deal with someone who was so transparent and not aggressive at all. When it came to signing paperwork Fay Demos shocked me, she was able to beat my credit unions rate. Went in under the impression I was going through my credit union, and nope she beat it. Both Kimberly and Fay went above and beyond and definitely earned my business. I would highly recommend anyone shopping for a Mercedes, or used vehicle, to buy through them.

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

Was a great visit. All as planned. Fast, communication from Dean was great. Could not be happier with the warranty repair and the smooth process to get it completed.

I recently visited the dealership in the hopes of learning more about Mercedes Benz. The sales team was professional and very knowledgeable. I don't normally enjoy car buying, but this experience was completely different. Professional, friendly and no pressure! Great service throughout the entire process. Thanks to the entire team for all your help!
