I was actually looking to purchase another car, but ended up seeing another Cadillac to my liking. Aaron, Bennett, and Sherrie made my simple deal even more easy with their outstanding customer service. Treated me like family and we even watched the Kentucky Derby together after the deal was done. Highly recommend Cadillac of Naperville. Love my CTS!!!

Had a great experience ordering the Cadillac Lyriq thru Heritage Cadillac. From start to finish it was a pleasure dealing with Elizabeth and Isaac. They did all the work.. I highly recommend Heritage Cadillac and I looing forward to getting this awesome Cadillac. Thank you.

With the customer satisfaction at the center of their focus, my buying experience it was great. No pressure, no hassle.

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 glad that Maxwell was knowledgeable about the vehicle I was interested in. It was a good experience.

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!

We started out knowing what car we would like to test drive. From the moment we walked in the door we received a warm welcome and everyone we met was extremely nice and wanted to help. The only annoyance, and it really is unavoidable, is the amount of time from beginning to end it takes to purchase a car. Our salesman, Mark, was knowledgeable and informative, helpful and honest and engaging. Would highly recommend him.

Cadillac of Naperville is a first class dealership in every sense of the word. The staff is friendly, knowledgeable, respectful, and every department has a great group of people. The facilities are spotless and very inviting as well.

We drove 3 and a half hours to go to this dealership. We could not have asked for anything more, these people are top-notch people. This place was clean, people were friendly and helpful. John O'Connell Was our salesman and we could not have picked a more perfect person to work with. We went in to buy a Yukon AT4, left with the Yukon, and purchased another car from them. We have found a car guy and dealership that will always have our business.

dealerships on how to treat customers!!!! This was the BEST dealership experience we've ever had in our lives!!! Chris Dargan was amazing!!! He was courteous, professional, knowledgeable, and treated us with the utmost respect. Chris never tried to overcharge us. Bert Dutcher was awesome as well!! Bert was upfront about everything and never once did he try to convince us to use their financing. Bert was professional, kind, personal and patient. The only bad thing about Bert was that he wasn't a "Dallas Cowboys" fan!!!! When you're ready to purchase your vehicle and you want to be treated with dignity, come to Rizza!!!

We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

John Giuffre made the buying process stress free. I would recommend going here for your next car buying experience.
