Alex Alverio
Alex is the man to see he knows his vehicles. Easy to talk to great customer service, he finds the vehicle you need. Alex help us in every aspect. Would highly recommend this dealership and recommend you all to see Alex.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I had an amazing experience working with my salesman Antoni. He guided me and my family to the best car that suited us. He makes the car buying process super easy and smooth. The car was also a very good price too!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

One hour twenty minutes from walk in to drive off
This is the second car I've bought from CarMax (I also once sold a car). Every experience has been fantastic but this actually ranks as the best. Sales Consultant LaShinda John answered every question I had via email and then, for financing, by phone so that I walked in with the exact make, model and trim I wanted waiting for me to test drive and pre-approved for financing. The entire in-dealer experience took less than an hour and a half. Fantastic company and fantastic sales consultant.

Ask for James!!!!!!!!
Keeping this short and sweet. I call Adam Auto to On Saturday 11/11/2023 I called Adam Auto Group of Crestwood, Il to inquire about a vehicle. The salesman James answered all of my questions. It's hard to get a salesman to answer questions over the phone they all usually want you to come in right away. He did not pressure me in any way to come in. After a few minutes he called me back and gave me more details about the car, it was close to closing but he convinced me to come in to see the vehicle for myself. When I arrived he took me out to see the car and it was everything he said it was and had every amenity I was looking for my new car to have. He was very polite, professional and knowledgeable about the vehicle. His professionalism and patience with me was what I enjoyed most. Before I left I put down a deposit to hold the vehicle. Today 11/13/2023 I went back and got my car! Please ask for James if you decide to visit Adam Auto Group he will not disappoint!

Great place and people!
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.

Replacement Rear Window Wiper Blade Cover
Somehow the rear window wiper blade cover on my 2019 Buick Encore went missing.... Being a long-time friend and customer of Mike's, I went to his GMC service center for replacement, and was grateful that Bill Haggerty replaced the missing cover without charge! As always been my experience, GREAT service and GREAT dealership! ...Tom Noble
