Ive bought at least 20 trucks from Perry Cogburn over the last two decades. His service is undeniable. Delivers each truck to my doorstep. No reason to search anywhere else. Top notch. I’ve referred several friends to him who are still using him. Randy

Donovan was great to work with.
Donovan was great to work with. No pressure, knowledgeable, told the truth when he wasn’t sure about an answer, then researched it. He used to be an assistant service manager, so he knew a lot of mechanical stuff. I recommend working with him.

Sweet White Sierra XLT
I found myself in need of a vehicle and looked at different options. I finally settled on a 2018 Sierra. I went to Weld County Garage because I serviced my other vehicle there and was impressed with the quality of service and the friendly atmosphere. Perry Cogburn showed me a number of vehicles and we worked a deal on the one I purchased. The process was very easy with no pressure. I highly recommend Weld County Garage and I'll continue shopping there.
