I had a great experience as a first time buyer from a dealership and my sales representative was extremely polite and very helpful in helping me purchase a vehicle that I liked.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

This is the Dealership!
I toggled between 4&5 stars and I landed on 5 (which is hard to do with me)and I will tell you why.I started out with BMotors over a month ago looking at one particular 5th wheel and after it had been listed that it had some things that worked it actually didnt but well my son was a used car dealer for many years and this was the reason I asked for it to be checked.I know how things work in used vehicles its not always obvious even to the dealerships. They could have sold me it as it was but they were 100% honest and said they needed to put me in another trailer.This is the most important aspect of a dealership really. You get what they are saying! This new 5th wheel is more then double the price but its more then worth it and I am satisfied with it They did good by me and in house financed me on top of it. Bret was amazing and answered every time I text him a question or concern. When I was ready to haul this giant 5th wheel for the very first time with a truck I just purchased they actually had their service guy (and another employee follow)drive about 6 miles with me to get me out of the city and show me how to make the turns and show me how to use the brake system on the trailer.This is above and beyond!! This Yall is a 5 star Dealership!!! I highly recommend Berkenkotter!! Go see Bret, Alen or Any of the Guys they eill hook you up!

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

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!

I had a great experience buying my truck sight unseen with the help of my salesman Tony he went above and beyond with pictures and videos that I requested that made me comfortable with my purchase it was everything he told me it was and more. He rode the sale all the way to the end and took care of every detail I would definitely recommend him to anyone who was looking at buying a vehicle from him especially if you were not able to be there 👍👍

We love the car that we purchased.
We love the car that we purchased. Our salesperson was easy to work with. We were cash buyers and the finance department handled that well. The only issue is that the car had received a minor repair in the rear fender and during the repair, the dealership failed to reconnect the tail light.
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

My salesman was Michael Meis at John Elway Cadillac, they treated me well. I purchased a used Tesla, they were the ONLY dealer that knew how to apply the IRS rebate up front. No hidden fees or scammy stuff. Michael Meis was great in sales as was Jonathan (manager) and the rest of the team, wonderful dealership experience which is rare these days.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I took delivery of my 2026 Suburban Z71 (6.
I took delivery of my 2026 Suburban Z71 (6.2L, custom Borla exhaust, red tintcoat) from John Elway Chevrolet on 23 October 2025, and I can say without hesitation that this was one of the best vehicle purchase experiences I?ve ever had. My journey with this dealership started way back in July 2025, when I first tried to buy a similar vehicle. That original deal didn?t work out, but Trevor (Internet Sales Manager) never dropped the ball. He stayed in touch, helped me custom-build the exact Suburban I wanted, and kept every promise, from the guaranteed price to a very fair-trade value on a challenging trade. Throughout the entire process, Trevor?s communication, communication, communication made all the difference. He kept me updated at every step as the vehicle moved through production and delivery. On delivery day, I met Amanda, who made what could have been an overwhelming tech setup feel effortless. She walked me through every performance and technology feature, connected my OnStar account, synced Apple CarPlay, and ensured I understood all the apps and settings before driving off the lot. Her professionalism and enthusiasm turned the delivery into a great experience. Daniel (F&I Manager) was equally professional, direct and knowledgeable when discussing warranty options, but respectful when I declined. The entire process was efficient, transparent, and team-oriented, which I deeply appreciate as a former military officer who values teamwork and integrity. When I left the dealership, my new Suburban was spotless, fully set up, and ready for a long drive south to Texas. I?ve bought many vehicles in my life, and I usually ask dealers not to put their decal on the back. This time, though, I left the Elway football logo right where it belongs. It?s a reminder of a team that truly earned my trust and my business. I not only recommend this team, would actively seek them out again in the future. Trevor, Amanda, Daniel.....a true pleasure to meet you all and thank you for a great experience. I hope to see you again in the not too distant future.
Best Truck I ever owned!
This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!
