If you are looking into getting a new vehicle, DO NOT go anywhere else! This was my first time buying a car and I lacked knowledge in what to look for or what to expect during the process. Frank Amadeo was incredibly patient and guided me every step of the way. I appreciated his honesty as well as his answering my every question. He strived to get me the best deal possible which he accomplished and than some. I was helped also by Kieth who was incredibly personable and aided me in the process, as well as Luis who guided me through my new vehicle technology as well as talked through my questions I had about my vehicle. Overall I could not have asked for a better experience, I will be telling everyone I know that this is the place to come for all their vehicle needs. Thank you!

I recently had the pleasure of purchasing a Cadillac from the Naperville dealership, and I can't speak highly enough about the outstanding service provided by Sales Associate Max DeMare and Finance Manager Sherri Pacchiano. From the moment I walked in, Max's friendly demeanor and deep knowledge of the Cadillac lineup made the selection process seamless and enjoyable. He patiently answered all my questions, ensuring I felt confident in my choice.​ Sherri's expertise in finance was equally impressive. She walked me through all the available options with clarity and professionalism, making what can often be a daunting process feel straightforward and stress-free. Her transparency and attention to detail were truly appreciated.​ The level of customer service I experienced here is truly commendable.

Alex Sanchez helped us purchase our new to us Expedition Max Platinum and he was such a great salesman from start to finish. Kind, honest, and detail oriented. Thank you, Alex!

An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!

My name is Judy W and I live in Chicago. I saw a 2019 Cadillac CTS Luxury AWD in red with 13,000 miles and Certified. I called and Claire, my Sales Consultant, went above and beyond to tell me the near mint condition of the car. They did not charge me with any additional nonsense fees and came in to the store and traded out of my 2017 CTS. Napleton Cadillac Oak Lawn was a great experience and will send my friends and family there.
