Purchasing a vehicle can be very stressful, we did not get that while discussing the potential purchase of a new vehicle. Jovanni was very patient with all of our questions.
Great truck to own.
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.

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

Sold my car to Autonation.
Sold my car to Autonation. It was an extra, so we weren't replacing it. Of course, a dealer paid wasn't great. But Chris Corringan was great to work with. He did exactly what he said he would do, WITHOUT any bait-and-switch tactics. When we're in the market for another car, we'll definitely give them a first try.
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!

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.

Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.
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!

Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan
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!

I was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!
Exceptional truck with one annoying detail.
I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

Craig T made purchasing a new vehicle from AutoNation
Craig T made purchasing a new vehicle from AutoNation Chevrolet North a real pleasure. He was able to coordinate the purchase, final prep, and delivery of the vehicle. I?m extremely happy with my experience purchasing an Equinox EV RS! Craig, Freddy in service, and the General Manager all made the experience extremely positive. I very strongly recommend both the sales and service departments. Ask for Craig. He will set you up with a vehicle that will serve you well!

Pleasant and friendly We were treated with respect and kindness Would buy another car from this dealership and sales Person. Our last three cars were purchased from this dealership and we will happily do that again next time
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

We had a great experience with this dealership!
We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

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 own a 2023 Sierra 1500 Elevation equipped with the 2.
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. :)

We just purchased a car at Mountain States Toyota and are extremely impressed with transparent, straightforward experience. They have an extensive inventory and the salesperson, Hunter, is an asset to the dealership. Hunter's customer service was the main reason we bought a car here. His knowledge is amazing and either he answered our questions or researched them and followed up. Just a great experience!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

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.
