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

Jared the service advisor was very polite and helpful . He provided proper assistance with the service of my vehicle.

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.

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

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.

After extensive searching I found a truck at summit auto center that matched my needs. After deciding to buy the truck, the whole process was actually easier than some local deals I have made. The condition of the truck is outstanding! At 6 years old it is in a condition that one would expect of a 1 to 2 year old unit. I am very pleased with the deal. A search for any trucks I may need in the future will start at Summit Auto Center

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!

My recent purchase from B & M is probably the best dealership experience I’ve ever had! Dominic and Chuck were friendly, extremely knowledgeable and helpful… B&M has a great selection of vehicles, a great service team, a wonderful sales team and the showroom has some CLASSIC cars that you can view as you wait! 10/10 recommendation!

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.

Great service. The service department was courteous and friendly. My car was serviced and ready to go in a reasonable amount of time. I was very satisfied.

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 .!

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.

Thanks to Woody Buick GMC for another great experience in purchasing a new SUV. We’ve had the pleasure of leasing and purchasing 8 vehicles through Brian Newcomb over the years and he never disappoints! He always finds us just what we are looking for and makes sure we walk away as happy customers. If you are looking for a new vehicle, Woody Buick GMC is it!

Sam S. My sales rep. Was patient and honest. His no pressure approach was refreshing compare to the other dealerships I went to. They were quick and efficient. Repeat customer.

Dealt with this CarMax dealer over the phone and email. Tried to negotiate a price based on other dealers in the area for the same vehicle and was told that the price listed was the price you pay!

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

Bought a car for my daughter tim was great would definitely go back for my next purchase

Another positive experience! Kevin Holman was very professional and continues to provide excellent service.

Had my truck in for service at Willowbrook Ford where I purchased the truck. This is not the first time I’ve had service performed there. The service was always excellent. Service advisors are thorough, friendly and knowledgeable. Service was performed in a timely manner. Great service!!

Excellent help with trading in my used 2016 Chevy Silverado. It had some right side damage, but Victor and the sales staff helped me out with a trade in.

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.

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.
