I was interested in a new GMC Acadia, specific features
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!
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. :)

Great Buying Experience
Look for Lindsay she made buying hassle free after a long day at work. Once I was in finance Leonel had the paperwork ready and it only took a few minutes to complete the sale.

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 have purchased a few cars from this dealership. Each time they have been fantastic in how they worked with me and treated me. As a result of my experience, I trust when I purchase a vehicle for me or my family, it is done with the best intentions and outcomes. Sean Goodgain took his time to make the encounter personal.

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?

We purchased our vehicle from Berkenkotter Motors and we couldn't be happier. We came from Brush in search of a 4 runner and the experience was well worth the trip. Lucas and Dan were very honest, helpful and treated us with respect. They were easy to work with and made us comfortable with our purchase. They made the buying process stress-free and they ensured everything was handled smoothly. I highly recommend them. Thank you so much guys! We definitely recommend your dealership and look forward to working with you more in the future!
My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

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.
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!

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

Bought my first car in 12 years and Marco made the experience very smooth. He was great in explaining my options, talking about the various models I was looking at and working with us on finance packages. I had some concerns about a couple tears in the upholstery and Marco was proactive in finding a solution that helped me make my decision. Thanks, Marco!

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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.

The best car dealership in Colorado My sales person Leon is such a great person. My experience of the dealership was one of the best I ever had. I recommend anyone buying a car please go to Rocky Mountain Euro sports and if you do ask for Leon honest Very caring and just a great person yes, my experience was the best this person gives a 10 from me
I've had the truck a month, and so far so good!
It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Very nice and friendly staff. Excellent service. Explain and answer customers FAQ . They have different models and deals for every customer what ever your style or your budget.
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 traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.
