Used GMC Sierra 1500 trucks for sale near Sycamore, IL under $599,963

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

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 !

What a great buying experience! Chris, Brandi, and Dan made the purchasing experience super easy!!! No pressure, no gimmicks, no swindling…. Just an EASY and relaxing purchase. Way 2 go team!

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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 have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

Alexander Lopez was great to work with, hopefully he sent that cup and shirt. Wonderful experience.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Professional, treated me the correct way to help me purchase a price. Sales guy was super cool and down to earth

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Great people to help in getting the car I wanted. The service to make things happen that insured trust and honesty was greatly appreciated. Thank You.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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!

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.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

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.

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.

Only place to purchase and sell a car outstanding experience outstanding quality cars and Kudos to everyone I encountered. Clean and efficient world class above everyone else in the industry

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Wonderful customer service, amazing financial people, overall amazing experience! I’ll definitely be back again

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Thank You for an Exceptional Buying Experience Dear Andrew and Alex, Thank you so much for all your help with my recent purchase of the 2024 BMW X3. You made the online and over-the-phone buying experience truly enjoyable. Your friendly and approachable attitudes made me feel welcome from day one. I also really appreciate your fair pricing and outstanding customer service—especially delivering my BMW all the way to Peoria, IL. Your efforts have left a lasting impression, and I will surely return for all my future auto purchases. You both went above and beyond, and I’m sincerely grateful. Thank you again for everything. Best regards, Jamie Peoria, IL

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.

I just got my Tesla at Affinity. Milton was amazing. He knew exactly what I needed. I strongly suggest that you go see him before EV credit is over.

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.

All in all this was a very pleasant car buying experience. Tom Dempsey, the owner of the dealership, personally found me the car I was looking for at the price I could afford. Elijah then took over and did an amazing job showing us how to operate all of the electronic features this car has. He was extremely professional and patient and he walked us through everything. I will recommend this dealership to all my friends.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

From the very first contact, through the entire sales process and right through to delivery, the service from Ramy has been absolutely first class. Everything was handled with professionalism, transparency, and genuine care, making the whole experience smooth and stress-free. Ramy was knowledgeable, attentive, and always willing to go the extra mile to ensure I was completely satisfied. The dealership itself is amazing, and the level of service provided was faultless from start to finish. This was one of the best car-buying experiences I’ve had, and I’ll definitely be coming back for future purchases without hesitation.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Joey Dalporto assisted us with our purchase of a used Buick Cascade. He was very approachable and helpfully answered all our questions. It was a great car-buying experience.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

This was a great experience and Mike was awesome to deal with. There was no pressure to buy and he answered all our questions promptly

Very friendly. Very helpful. They had my dream car. I live 2.5 hours away from them. Alot if our interactions were over the phone. Needless to say, 7 days after our first interaction I drove away in my dream car. They are definitely worth checking out. If they have a car you want, they will do everything they can to make sure you get your car.
