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

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.

Extremely friendly and professional people. I would buy from them in the future.

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.

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.

Sales rep (Kenn) and GM (Bradley) were awesome to work with. Just the kind of buying experience everyone is looking for. Highly recommended!

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.

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 absolutely love my brand new E350!!! The dealership was excellent. I felt like I had a trusted advisor in Liz! I would highly recommend her if you’re looking for your next Mercedes-Benz!!

it was just some presales questions and they were quick to reply and offered a lot of assistance.

The dealership contacted me and followed through on everything I asked and needed of them. Great overall experience.

Mercedes c class. I believe this is the 3rd car I have purchased from Autohaus. Very comfortable feeling

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.

This is really a great place, they are so busy it is amazing. Pricing on some cars are fantastic. I just sent a friend there to look at one and it was gone by the time she arrived. I'm sure she'll find another. We bought an SUV, but I am also in the market for a sedan! This will for sure be my Go To place!

This is one of the best Mercedes dealerships if not the best in the Midwest region. They ALWAYS do a professional job and take good care of me

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.

Valerie is a pleasure to work with. she?s very helpful and very attentive to our needs. She takes a complete look at our auto needs and never oversells services that we don?t need.
