I bought this after going to the dealer just to look at
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.

I have bought a car previously from a Weber dealership
I have bought a car previously from a Weber dealership and have service work on my vehicles done at Weber dealerships. Based on my previous good experiences with Weber dealership I went to a Weber dealership when looking for a new car. Ben Vogt my salesman did a wonderful job of answering my questions and helping me with the paperwork. Since buying the car Ben has answered questions worked with me to purchase my car. They worked with me so I could move money around so I could pay cash for the car.
Overall I am very happy with my new Truck.
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?

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.

2022 GMC Sierra SLT 3.0 Duramax
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 experience with Hayden was great. He was knowledgeable, courteous, and willing to present my offer on the vehicle. I ended up purchasing in my home state but would highly recommend them based on my experience with them.
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

We had the pleasure of working with Billy Willis. He was so knowledgeable and placed zero pressure on us. It was by far the easiest experience we’ve had. We couldn’t be happier with our 2022 Tucson or with the service we received from Billy!

2019 Sierra SLT X31
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

such a friendly company.
what a great dealership. there was no selling, they educated me. I know what I wanted almost and they filled the gaps. Every time I go in there I get treated as part of the team
Great truck!
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!

Excellent Service!!
I was in an accident and my car was totaled. I wanted to replace it with a new Nissan Rogue, it the car dealership that I got my last one at was no very anxious to help me find one since I hadn’t received the check from th insurance co. yet. Todd Eversgerd went out of his way to find a car, get the extras that we wanted installed on it, kept in contact with me re: when the car was delivered and the work was done, etc. He even went so far as to try to match the color of paint on the number of our license plate that had been scraped off during the accident! Eva’s very professional and went above and beyond in all aspects. When we got there, he was busy with someone else across the street at the VW dealership, so he had Matt help us wile he was over there. Matt also was excellent. He went over everything that Todd had written down including giving us the manuals, having us watch the videos, introducing us to the finance manager. Afterward,Matt took us out to the car went over everything about the car,and programmed our phones into the car. He then called Todd so Todd could make sure we didn’t have any other questions. I have never had anyone go to the lengths that stood went to make car buying so easy.Will definitely be back for our next car!
Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!
