Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
One very awesome vehicle.

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.
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.

Great Service! Quality Vehicle!
I spoke with Adam at the Sterling Auto Sales Franktown dealership looking for a specific vehicle at 4pm. He had it delivered to them the next day as I traveled from out of town. The vehicle was ready and warmed up for me to test drive when I arrived. No high pressure sales, the vehicle was clean, loaded with extras, and drove perfect. All my questions were answered and the sale was fast and smooth. I am very happy with my purchase. I would highly recommend this dealership.
Very beautiful truck
This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Great experience, good people
I was in the market for truck and messaged Ryan after finding a great deal off the Sterling Auto website. This was one of the easiest, stress free, no pressure experiences I’ve ever had purchasing a vehicle. I was in and out the door in under 2 hours. Highly recommend. Everyone I met with was kind and straight to the point. I highly recommend and would happily do business with them again.
Happy Customer
I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

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!

Great Experience
I had been shopping online for several weeks, had three or four vehicles picked out that I really liked. Sales person Dominic was very helpful in showing me everything, was not "pushy" and worked out a good deal for me. I Love my new/used Jeep Compass!!
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.

F-350 Diesel
Abe with Truck Kings found me my dream truck and brought it to me with everything customized to my taste-even down to the interior floor mats. He had all the connections to get me financed and the entire process was quick and easy. no detail was overlooked from tires to windshield. I would highly recommend if you need a new ride to stop by see what he has to offer.

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.

Our experience with Jason Montgomery was absolutely
Our experience with Jason Montgomery was absolutely fantastic! From the very beginning of our car search, Jason went above and beyond to help us find the perfect vehicle. He was incredibly patient, knowledgeable, and genuinely cared about making sure we found exactly what we wanted. When it came time to go over our new truck, Jason took the time to explain every feature in detail ? making sure we understood how everything worked and felt completely comfortable before we drove off the lot. His professionalism, friendliness, and thoroughness truly made the whole process easy and enjoyable. We couldn?t be happier with our new truck or the amazing service we received from Jason. If you?re looking for someone who truly goes the extra mile, Jason Montgomery is the person to see!
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
