2020 GMC 2500 AT4
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.

One of the best buying experience I’ve had in a long
One of the best buying experience I’ve had in a long while. Jeffrey was great. Had everything prepared for our appointment. The truck was cleaned up and ready for the test drive. Once we got back we worked on the numbers. They were close, but working with the sales manager we agreed on a very fair deal. And that’s what I appreciated the most let’s be fair with each other. The next day working with Preston in finance was also very pleasant, he worked his magic and got us a great rate with the bank. Overall experience was excellent! I hope I won’t need another truck for while, but if I do I hope the three guys are still working here. Cheers to them. Ask for Jeffery(sales).
One very awesome vehicle.

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 bought a new Subie from these folks and the whole
I bought a new Subie from these folks and the whole process could not have been easier! Everyone I dealt with was very helpful and efficient. I was able to arrange pretty much everything via phone/email ahead of time, and once at the dealership, very quickly I had finalized the purchase and was headed home in my new car! No surprises, no games or hidden charges, no high pressure sales. Everything was clear and very straight forward. It was definitely worth the long drive for me to go up to Denver for the purchase.
2019 GMC 2500 Denali Excellent Condition

I came in for an oil and oil filter change.
I came in for an oil and oil filter change. During the initial inspection, Jack, the service advisor, identified a problem that could have left me stranded. Jack coordinated the repairs with the technicians and I was back on the road in just a couple hours. A HUGE ?Thank You? to both Jack and the service technicians.
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.
