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.

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

I purchased my car three years ago, and every time I return for my service appointments, the staff is incredibly friendly. The entire experience, from making the appointment to receiving my car back, is top-notch. I have my own service advisor, Steve, who is amazing. He explains everything clearly and ensures that I understand my options. Steve excels at his job and at building a positive relationship with me. He also keeps me updated by texting while my car is in service. Additionally, the dealership recently underwent a remodel and looks fabulous. They even have a chef who prepares breakfast or lunch when it’s ordered—how great is that? Cooked to order and it’s FREE! My sales representative, Bill Harris, is honest, knowledgeable, and patient, truly an all-around good guy. He even calls me to remind me of important dates related to my car and my birthday, which is such a nice touch. I'm going to be a customer for life! Great job, everyone!

My service advisor Josh Ruiz is excellent in his job and attention to details were great. My SUV had a service B1 and 2 recalls on my visiti but Josh finished everything as promised, service was done ASAP? great job Josh and all who worked with my EQB 300.

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