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.

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.

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?

Im a first time buyer.
Im a first time buyer. This is like the first major purchase I?ve ever had. I was beyond clueless but Alexis walked me through every step of the way with utmost patience. We were there for hours as I asked so many questions and she didnt mind at all.
I have the 1500 double cab with standard bed.
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.

Steven in the Service Department was professional and efficient. He listened to me, addressing not only the issue I was having with the vehicle, but WHY it happened. And then solved both problems with a timely fix at a very reasonable price. Historically, I steered clear of Dealerships for service issues. That's likely to change after my experience at Colonial South. Good stuff. Thank you to all involved.

Just purchased/leased a 2026 Trailblazer. Stanley Thornton was the AutoPlex rep. Very knowledgeable about the brand, including pros and cons. His communication skills are extraordinary. His dedication stems, in my estimation, from his veteran background. solid character, give him a call !!! Dayne Luce.

After recently having a terrible car-buying experience
After recently having a terrible car-buying experience where I was taken advantage of and ended up with a lemon, I was extremely cautious about trusting another dealership. As a single woman shopping for a car, it can feel overwhelming trying to determine who is being honest and who truly has your best interests in mind. When I found the vehicle I really wanted, I hesitated because the dealership?Arlington Nissan in Illinois?was out of state. I spent nearly two months continuing to search for other options, but nothing compared. Eventually I decided to take the chance and make the trip to see the car in person. From the moment I arrived, the experience was reassuring. Alex Reiss, the salesperson who helped me, was professional, respectful, and refreshingly straightforward. Even though he?s a younger guy, he handled the entire process with confidence and integrity. He listened to my concerns about my past experience and made it clear that this time things would be handled differently. Alex answered all of my questions, provided the reports I requested, and explained the 6-month Certified Select warranty, which helped give me peace of mind. Because of how transparent and helpful he was, I felt comfortable enough to move forward and purchase the car that same day. The experience in the finance office was just as positive. Dominic walked me through the paperwork carefully and made sure everything was clearly explained. I really appreciated that he didn?t pressure me into unnecessary add-ons or try to slip in extra warranties or fees. The process was honest and straightforward. Before taking the car home, the dealership also addressed a few service items I wanted looked at and completed a full detail. Kiah in the service department kept me informed about what was being done and when the vehicle would be ready. When I returned to pick it up, the car looked fantastic?honestly like it had just come off the showroom floor. The service team clearly took the time to make sure everything was done right. What stood out most about my experience was the team effort. Alex, Dominic, and Kiah all worked together to make sure my concerns were heard and that the entire process went smoothly. They treated me with respect, were transparent throughout the process, and delivered exactly what they promised. Buying a car after a bad experience can be difficult, but this team truly restored my confidence. I would absolutely recommend Arlington Nissan to anyone looking for a vehicle?even if you?re traveling from out of state.

Honest, friendly, experienced staff. Worked with Landon, Connor and D. They did a great job and worked hard to gather details for me and keep me informed. The lobby is nothing special and don't expect anything for free. Negotiations were straight forward, no silly games on the used vehicle sale. Didnt get everything I was promised (Call back, delivery, gas card, other details) but it was good enough. Thank you!
