Used 2020 GMC Sierra 1500 trucks for sale near Berkeley, IL

Mario did an awesome job with the customer service and did not feel pushy at all. Mario did everything he could to make a great deal that my wife and I could agree on. Mario and I connected so well that we decided to network after. Awesome customer service and awesome people. Thanks again!

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

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!

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!

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.

Excellent service even delivered the new car door to door very convenient. They made the whole car buying process very easy. I would highly recommend them to anyone who is interested in a buying a new car.

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.

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.

Michael was great and very informative!!! I will definitely continue to visit this dealership rather than the one closest to my house.

I received a recall letter. I was actually able to get an appmt the following day. It took 55 min. They told me about an hour my service advisor Vince was great. All good

We've worked with Tony before & he is very knowledgeable & knows just what we like.

Nicest staff, from first phone call to driving away in my new truck in a little less than 1 hour

Sold a 2018 Honda Civic 2 dr coupe on Friday, 11/14. Alex was absolutely great. They purchased the automobile for exactly what they had quoted. We will never sell or purchase with any other dealership! They were fair and honest which is not true of many other dealerships. Would recommend whether buying or selling. Do not waste your time with anyone else.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

Had the car out front ready for me when I got there. Everyone very friendly

Had a very pleasant experience leasing my Audi. Did 90% of the deal over text and email. It's easier for me as I have anxiety issues and most dealers I've tried working with won't accommodate. Ed and team are excellent to work with and would recommend this Audi dealership to anyone looking for a vehicle.

I've been purchasing automobile from Haggerty in Villa Park for OVER 25 years. Also have them serviced at the Villa Park Haggerty location and body work done at the Glen Ellyn Chevy location. Good people and great service,

Great Cars and also good service. Vincent Vega was very helpful thank you Vincent for all your help. This is our third car from Castle Buick GMC. We loved thank you .!

The entire sales process and especially Both of the Salesman Ryan -And- AJay were Great! Highly recommend the Adam Group Car dealership to Anyone!

Anthony, Kaitlyn, and Brian were great to work with. This was the easiest dealership I have worked with. I was in and out in under 1.5 hours. Anothny and Katilyn were efficient but also made sure that everything was covered at the best price in town. I recommended anyone to go see Kaitlyn.
