Used GMC Sierra 1500 SLT for sale near Elgin, IL

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Really good service and attention to my car. Did the gorgeous job and kept me abreast the issues with the car. Love the Services and skills.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

We had an excellent experience from start to finish. The entire process was smooth, professional, and very welcoming. A special mention to Ramy, who truly made a difference in our experience. Ramy went above and beyond to ensure everything was clearly explained, and was incredibly helpful, patient, and friendly throughout. It’s rare to come across someone so dedicated to providing great customer service. Thanks to Ramy’s support and professionalism, the whole experience felt easy and enjoyable. I would highly recommend this place to anyone looking for quality service and a team that genuinely cares about their customers.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Matt in sales is extremely professional. His knowledge of the vehicle was obvious. He throughly explained the car's features with me. I'm glad he was my sales representative with the Castle Subaru dealership.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Thank you again Zone Motors for my beautiful car, I purchased a 2011 Audi A8 and I couldnt be anymore happy. They got me in and out within two hours. I will definitely recommend to friends and family.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Elvir and Matt did a great job and I was pleased with the attention, negotiation and the car I got.

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.

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.

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!

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.

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.

Service is great and friendly and they will do everything they can to make sure you get your car in and out no problem. They’re awesome! -jimmy sands

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 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 .!

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.

This dealership was recommended to me after a couple of bad experiences at the one I had before. Harvard ford will be my main dealership from now on and I'm from Rockford. Top notch from the service department to the sales department and everyone else in between. Took care of my issues and explained everything with professionalism. 5 stars for Harvard Ford

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

The best experience at a car dealership. On the 1st day, we were received by Eric Goddard. He was extremely patient with us. We test drove Ionic9, Ionic6, Ionic5, and Pallisade. He was smilling all the time and answered all our questions patiently. He was the reason we visited the showroom the second time to finalize our purchase. However, he was busy with another customer and we met Dillon Strack. He was equally nice and patiently answered all our questions. We test drove the Ionic9 again - just to make sure we investing well. We loved the vehicle. After spending 5-6 hrs at the dealership, and having innumerable conversations with the Manager Mark, and negotiating the price and accessories, we came home with our new vehicle. We love it. And we truly had a great experience at the dealership. Thank you - Eric, Dillon and Mark.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

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

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.

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

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.

Bought my car on a busy Saturday Luis P was helpful and efficient when I bought my Mazda.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Our salesman Brian Newcome was polite, professional, knowledgeable, and personable. We felt he answered all our questions, and explained the process so it was understandable. When you buy a car you wonder did I get a good price and make the correct decision, with Brian there was no concern about that at all. I would recommend Brian and the dealership to my family and friends.

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!

Great experience with this dealership. I will come back again as well as refer my friends and family to this dealership. Sales guy Dan was a big help!

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 !

I always buy my cars at willowbrook ford/kia. Go see Tom if you want a Ford, and Mike if you want a Kia. They are helpful, friendly. Great place to buy a car

Kunes Woodstock service department did a fantastic job of getting my vehicle in and repaired in a timely fashion. Becky, Eva and Dannielle always go above and beyond to provide the best service experience possible.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Very good selection of cars and a highly professional staff. The whole system was very well organized, which made the experience smooth and stress-free. I’m very happy with the service and would definitely recommend to others.

I really like my nw, to me, 2015 GMC Sierra Denali. The salesman, Terrance Lin was very efficient, helpful and courteous. Thank you very much.
