Great Place!
Hany was honest and nice and everyone was so attentive. They actually filled my tank with gas and washed it before I left. Wow! I'm telling everyone I know about the service here. The price was very good also.

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.

As always quality service.
As always quality service. Knowledgeable people handling vehicle. Great waiting area and the offer of water. Sales floor could be a little more accommodating to the customers needs.

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.
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 had a great overall experience.
I had a great overall experience. From the moment I bought my car off the lot to every time I bring it for service or maintenance. Not only are they very welcoming but they explain everything in a way that I can understand easily.
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.

Excellent service from my salesman, Tony Lafreniere.
Excellent service from my salesman, Tony Lafreniere. Highly recommend him. Took away a star due to all the dealers extra fees but ultimately we compromised and the sales manager was not pushy.

I was interested in test driving a Nissan Kicks . We were assisted by Mason who was very helpful and knowledgeable . He explained everything to us about the vehicle. A lot of the things were so new to me since I had been driving a 2009 vehicle. We enjoyed working with him and everything went smoothly with the purchase. Thanks again to Mason Nash on our purchase .
