Kelly S. from Frederick, CO, whose Audi was in for an auto repair, on 12/5/2016:
"After several discussions and a very detailed estimate, I decided to have a new-rebuilt engine installed in my Chevy S10. The work was done quickly with only a few minor additional parts needed to provide a virtually new truck with a warranty. Additionally, Hayes helped with the cost of a rental vehicle that made the experience seem a little more special."

Jeremy P. from Longmont, CO, whose Jeep was in for an auto repair, on 11/11/2015:
"I found Hayes by researching online and reading reviews on various websites. They clearly had done many things right, to gain the trust and loyalty of their customers. My own experience was excellent! I brought Chris my 2005 Jeep Rubicon (4 inch lifted) with several drive train and suspension related issues. Not only did he do a great job of investigating and estimating, as the inevitable gremlins arose, he presented options at various price points and kept me appraised of the current project cost. His professionalism, enthusiasm and delivery were spot on and helped me prepare for this complex and costly endeavor. In the end, I'm very happy with the improvements and the cost. My Jeep rides even better than my expectations. Thank you!"
