Used GMC Sierra 1500 trucks for sale near Gilberts, IL under $20,000

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.

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.

Excellent service and knowledgeable. They Found me the best Subaru for my needs and preferences. Listened to all my questions and Concerns. Extra care all around from sales rep. Greg, manager Noah and finance George. I will look forward to maintaining my Outback purchase with Castle Autoplex in McHenry, IL.

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.

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

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

Great site with an excellent selection of cars. The entire process was smooth and hassle-free, and I was able to buy with complete confidence. I highly recommend this site to anyone looking for a quality vehicle.

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.

went it to look at a car that i saw online, called to check if it was available, the moment i stepped in they made me feel like i was family and took really good care of me. Great customer service, and very friendly

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.

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.

Julian was great he helped us get into the right car. getting there we weren't sure if this was the car for us until Julian showed us all the features the car had. it was everything we were looking for. I will definitely go back when it comes time to buy my next car

It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

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

They have very bad paint peeling problem, they also have a hesitation at take off , good ride ,good interior comfort , fair fuel mileage fair power, we have two in the family, I am very disappointed in the paint peeling issue,I have a 2005 2500 paint is good.

My 2014 GMC Crew Cab looks and drives nice. I had no problems with St. Cloud Toyota. My sales person was wonderful to work with.

Great customer service, Alex helped me out with financing ! I recommend them if you are looking for a reliable car and good financing options!

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

Great people, selection and reasonable prices. I would recommend the dealership for new or used car purchases.

Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

Great service and easy financing!!! Got my first car from here with extended warranty. Thanks for your service

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

They have a lot of trucks for reasonable prices. I recently bought a 2013 Ford F150 came out very clean. It runs good and I recommend them to anyone else who’s looking for a good truck

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

But a very nice Nissan Sentra from them I was looking around and found out that they have very good prices and the quality is good too so thank you Andrei for helping me out!

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.

Thank you so much, Korey was fantastic! Great customer service! Easy and Fast! And Your Driving

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

Inquired when I located the car online. They responded in a timely manner and we set up an appt. Staff was very friendly. Price point and negotiations were very fair. No pressure sales. They handled all the paperwork, licensing and registration. The entire process was very easy.

I've had this truck for over 10 years, and holy cow it will not die at all. It has been in 3 wrecks and through the mud ect. Even if it "breaks down" it wakes back up in 2-3 minutes, my big GMC has gone through a lot in it's life time, pulling out cars and trucks bigger then it out of the mud. It even towed my 03 Ford F150 to a shop when it wasn't working, MY GMC WON'T DIE

Julian was great. He even took my car to a pre pruchase inspection to make sure it was the perfect car for me. Will definitely buy my next car from ace motorworks

The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

I bought a 2011 VW Routan from Auto Gallery. Steve went above and beyond to make my car buying experience painless and easy. Great guys to work with. Will recommend to friends and family.

This truck has almost every bell and whistle I can think of. It has completely exceeded my expectations. It is a smooth ride. It has all of the comforts I could need and more.
