Weld County Garage GMC Hummer review
Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!

I've been a customer of Markley Motors for over a decade. Just traded in my 2017 GMC Denali for a 2025. Hassle free process. Fair. Great trade value and always top-notch service. I'll be back.

Johnny in the service department went above and beyond getting our vehicle repaired. The vehicle wasn't purchased from Transwest but had an extended warranty with it. All of the issues were repaired and part of it couldn't be covered by the warranty. I felt like Johnny worked with us every way he could to make things right !! Thank You

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber
2026 GMC Sierra 3500 review
Overall pretty good, however it is undocumented if you turn off or adjust some of the safety setting it will cause light on dash to come on and make you think issue with system (ex collision if you change from default of alert and brake to alert only). I think this is an issue and should not light dash light to indicate an issue with the system because of alert settings.

Jose and the gentlemen who ran the numbers were absolutely amazing. My finance lady was so beyond amazing. They all were great and i had such a better time buying a brand new car then i thought it would be for my first time. Absolutely had an above and beyond type of experience. I'm so thrilled with my purchase and how the process went.
