Used GMC cars for sale near South Barrington, IL

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Julian was a great experience and very helpful liked working with him and his management

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Wonderful car buying experience. Tyler(Manager) and Dennis (Finance office) were absolutely crucial in making this car buying experience above the rest. Tyler took the time to explain pricing line by line so I had a full understanding of the total cost. Tyler also made me feel comfortable and kept the process low pressure and enjoyable. Dennis in the Finance Office was outgoing and friendly. Dennis again went thru pricing and made sure I knew what the final numbers were and explained every form I was signing, offered warranty options and went over cost and coverages. These two gentlemen made this normally stressful process enjoyable.

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.

The salesperson I met with was very pleasant to deal with and was good about getting back to me. It seems like there are no hidden fees and the cars are in good condition.

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 !

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 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

Compared the Nissan Rogue to the Hyundai Tucson for weeks before finally coming in. Viktor wasn't defensive about the comparison — he just asked what was holding me back and addressed every concern directly. The all-wheel drive system, the warranty coverage, the infotainment interface. He knew the answers cold. Drove the Rogue home that Saturday and it's been everything he said it would be.

Lisa and Larnell were great. Lisa made the car buying experience comfortable and answered all my questions. Larnell addressed my concerns and closed the deal. Great job guys!

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!

The buying experience with Jarvis was an absolutely wonderful experience from first handshake to driving off the lot. His professionalism and knowledge were apparent from the beginning. He also took the time to get to know me on a personal level through genuine conversations. It was beyond easy to see that Jarvis takes the utmost pride in his work. I am grateful for the entire experience with this gentleman. He is absolutely the best around! Highest recommendation on all fronts!

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.

Worked with Brian Newcomb and he was knowledgeable and personable. A pleasure to work with on our purchase.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Awesome service from Huntley ford and it's salesman Rob specifically. Huge selection makes car shopping in one place easy and convenient!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

I'm usually not someone who writes reviews but felt the need to since I had such a great experience here. From the moment I walked in, I was greeted with a warm welcome and great energy from the entire team. The vibe at this dealership was friendly, professional, and made the whole process feel comfortable and stress-free from start to finish. I worked with Alec Olney, and he was outstanding to say the least - extremely professional, personable, and clearly very experienced. He had answers to every question I asked and made sure I felt confident and informed every step of the way. I never felt pressured, just supported. Overall, a truly great car-buying experience. I highly recommend both the dealership and the team if you're looking for a smooth, enjoyable process.

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.

Kurt was awesome to work with! Beautiful car! Thanks, I’ll be back for the vet!

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

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.

The technicians, sales people and everybody at Naperville Chevy are just great!!! Totally different from other dealerships! They are a one of a kind dealership! Loving my 2026 Colorado!

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!

My sales person Alex Valdez was great! I thought he would give up on me because I was very picky and expected alot. I had resigned myself to keeping my current car, but then he found me the perfect vehicle and I love it! All in all it was a pleasant experience and I highly recommend McGrath Honda/Elgin. Just ask for Alex Valdez and he will work hard to find you what you want!

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.

The best buying experience ever.No fake add ons, straight forward prices. If you plan on buying new car that’s the place to buy from!!!!

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

Brain Salazar was my salesperson. He did a great job showing options and explaining the types of vehicles they offer. For the most part the team were professionals when interacting.

Anytime you want a reliable car I'd go to M'lady. If the car isn't reliable and safe they wouldn't even out it on the lot. Always looking out for the customer wants and needs. Doesn't try to push sales. Just wants to help. So I appreciate everything Jose and Scott

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.

Fantastic people and service, it’s what brings me back here. I could go anywhere, but because of the people, I come here.

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!

The whole process from start to finish was a pleasant experience. Lilly was very attentive and provided all information I need. It was not a hard sell, thus it was a pleasant, fantastic experience.
