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!

Transwest GMC Denver review
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

Shortline Buick GMC review
The service was top-notch. I had a broken mirror and worked with Greg Mudd, who found me a great deal on a mirror, painted it, and installed it, saving me about $350. He was incredibly kind and responsive. It was a great repair experience when I had been anticipating a stressful one.

As always the experience at Laura Buick GMC was excellent and we could not be happier with the vehicle we purchased. The entire team starting with our sales person went above and beyond to make sure we ended up with the vehicle we wanted at the best price possible. We have bought multiple vehicles from Laura Buick GMC and will continue to buy from them in the future.
