Used 2021 GMC Sierra 1500 trucks for sale near Bannockburn, IL

Antoni helped me get a great deal on BMW X5 he was really nice throughout the process and it was fast and easy.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I recently bought a 2014 Hyundai Sante Fe Sport that I found on Cars from Muller's and I am beyond satisfied. My sales agent Mike Stillwater was extremely personable and made the process very smooth and Jeff Glickman Finance Manager gave me the best finance and warranty options I could have gotten. They were even better than the pre-approval that I walked in with. All in all A++

Eduardo Del Rio helped me buy my ford explorer and made sure it was in my own liking

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Great experience. Alex was a charm to work with for the truck I been wanting.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

Great dealership, extremely knowledgeable staff and sales department. My sales rep, Justin, was incredibly knowledgeable about cars, which I am not, so I really felt taken care of.

I recently sold my 2014 Corvette Z51 to Diamond Motorwork, and the experience was outstanding from start to finish. I worked with Luke, who was incredibly kind, patient, and professional. He made the entire process seamless — even going out of his way to meet me at my workplace to pick up the car and finalize paperwork. His flexibility and attention to detail made it easy to choose Diamond over other offers. The price was fair, their reputation solid, and they took the time to ensure I was comfortable with every step. I especially appreciated how Luke worked around my schedule and kept everything stress-free. The owner, Rami, was also very attentive. While Luke handled things so smoothly that Rami didn’t need to step in much, he was present and supportive throughout — especially when I requested a wire transfer instead of a check. That extra layer of reassurance gave me real peace of mind. If buying from Diamond is anything like selling to them, I’ll be stopping in there first when it’s time for my next car. Highly recommend Diamond Motorwork for anyone looking for a trustworthy, respectful, and hassle-free automotive experience.

Thank you for getting my cehicle repairs done and workinf so hard to het me out of there to get to where I needed to go.

I recently purchased a car here, and Dan made the car-buying process quick and easy. He was honest, attentive, and helpful every step of the way. I bought a highly special used car, and Dan's knowledge and guidance made me feel confident throughout the process. I'm very happy with my new car and the service I received. I would definitely recommend Dan and this dealership to anyone in the market for a vehicle.

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

Eduardo gave me an amazing service at the dealership and helped me find a car.

Best dealer ever. Tatiana did a great job..She is very smart respectful and she has a lot of knowledge. My next car l m going to buy with them also and with Tatiana of course. If you are looking for a good price and a solid car go there and ask about Tatiana. Mike volvo v v90 cross country

Communicated with John Leno from the Schaumburg facility online. John understood my needs and responded quickly with Jeeps to review - after a bit of humming and hawing on my part, I changed my mind to trucks. I found a truck at another facility, John had it tranferred and within 2 days my soon to be truck arrived - and it is a beauty. John was training Matt and they both demonstrated immense knowledge throughout the interaction and I appreciated the ease of communication (not pushy). I cannot comment on the financing portion of the transaction, but closing went just as smoothly with Hubert and his supervisor. WHile impressed with my transaction I was also impressed with the amount of time that was placed on the training of new employees, or employees transferring. While yes my truck need a repair on the fog lights, it is covered under their warranty, I am highly impressed with my experience. From walking in the front door, to having John take my picture of me and my truck with a giant yellow ribbon... every individual at Carmax truly made the buying and trading experience a wonderful experience. Team Schaumburg, keep up the great work, each of you understand the true meaning of Customer Service, and that is important to some customers like me who still cherish old school values.

Best experience I've had when purchasing a vehicle. Everything was handled quicky and professionally with no pressure to consider anything other than what I had asked for. I was completely satisfied and would recommend this dealer and my sales associate Larry.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Risto was fantastic during the entire car buying experience. I highly recommend buying a vehicle from him. The entire Willowbrook Kia staff was easy to work with and made the process simple.

Very professional, excellent communication Friendly staff, and had the vehicle we wanted, would deal with them again

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs
