I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Jamie was a very great sales man. He took care of my grandma and worked with her. Very patient and helpful. ⭐️⭐️⭐️⭐️⭐️

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Wonderful experience! Brian worked with us to find a car for me within my limited budget. We went through several test drives before we found the perfect fit. Brian was great-straightforward, patient, and pleasant throughout. The financing process was quick and enjoyable. The entire staff was accommodating, friendly, and fun even though the process kept everyone past closing. It's rare to be able to say you had a good time buying a car, but I can honestly say I did. I look forward to working with them again in the future and I highly recommend checking them out for your next car purchase.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Nathan was amazing at guiding me through the purchase of my first Ford vehicle. I highly recommend him!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Big thanks to our salesman Brian for excellent service. Very through and he,Paul in finding the right vehicle for us. Prompt courteous service. A very satisfied customer. Highly recommend Woody and ask for Brian.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Worked with Tony Kretowicz. Tony was a pleasure to work with. Made the process simple and easy. He is a gentleman and I would recommend anyone to come in and work with him.

Great Experience, I would definitely buy from them again. Great service and nice people. Thanks.

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Healthy clean environment, that did not push me to try and purchase a car. They took there time in making sure all my needs are met and made sure all my questions were answered would certainly recommend this place to friends and family

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

What a great experience at D? Arcy Buick Dealership in Joliet IL. The staff was friendly, honest, and made the whole process easy. Ray our salesperson went above and beyond. I love my new Envision Sport and would definitely recommend D?Arcy Buick and ask for Ray!!

The dealership is one of a kind. The GM was loads of fun and took care of everything.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

Had a very good experience working with Sebastian. Got a fair price. Had an issue right away with the Honda Odyssey. Engine light went on but the problem was solved immediately. Turned out the oil was a little low. It was a used car. Machines are never perfect and almost anything can be fixed.

Had a great experience picking up my new Jeep Wrangler. Joe helped me out and they made sure the car was all up to date on service and was in amazing condition!

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

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.

Excellent sale team and service department is great only buy cars from D?Arcy team. Myself and family have buying cars from D?Arcy for years

Jorge was a knowledgeable salesman and made the process easy & fast! Very clean & inviting dealership. We were very happy with the whole process & everyone that assisted Jorgecwas great

Needed key fobs replaced. They were ordered and came in within the next couple days. Scheduled the service appointment and all was completed within two days. Have received great service upon all my visits.

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.
