Everything went smoothly and was a great experience.
Everything went smoothly and was a great experience. Everyone was so kind and helpful throughout the process. Devin Clark was very resourceful and easy to work with. 10/10.

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.

Great experience!
Great experience! Chris Lambert was my salesman he was very helpful and went over all the features of my new car. Financing was quick and efficient

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.

My service experience was excellent, as usual. This time was the best however, the issue was repaired within 90 minutes at a much more reasonable price than expected. Always love seeing the birds also.

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?

As with many auto dealership experiences, my interactions
As with many auto dealership experiences, my interactions with Shottenkirk Nissan had its ups and downs. However, I am giving 5 stars because there were two people that made the experience that good; our salesperson, Sommer, and the GM, Harmon. These two went above and beyond to answer questions and make us feel like our business was important to them. I highly recommend visiting the dealership to purchase from Sommer. She never pressured us or made me question whether she would just say whatever I wanted to hear to buy a car. She was honest, polite, and helpful. That is something that most salespeople lack greatly. Harmon assisted in the finalizing of the deal by being genuinely helpful during trade in process and answering all of our questions accurately about fees and taxes that appear on the buyers order. He eliminated the tricks and nonsense that many dealers do to grab a few extra bucks during the buying process. Thank you, Sommer and Harmon.
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.

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.

Honest, friendly, experienced staff.
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!
