8 years ago, I was a first year college student at UNC, driving a car suited for a 1st year college student that always was breaking down. Not only was Darren at The Wrench INCREDIBLE, kind, honest, and helpful, but so was every single mechanic there! 8 years later, I now live in south Denver and whenever I have car trouble still make the long drive up to Greeley to go to the Wrench. On occasions when my car cannot be driven, the guys at the wrench send a tow truck all the way to Denver to pick it up and give me a loaner car until it is fixed. There is simply no better mechanic shop in the entire state, or country for all I am concerned! My business will forever be loyal to Darren and the other guys at The Wrench! - Lindsay R.

I have used them for almost 10 years for my kids cars. They always take care of me and make sure the cars are good to go. - Gary S. (5 star review on Google)

We are new to Greeley and took our Camry in to have the timing belt changed. The guys that work here really have a passion for cars. Super nice and honest! We were told by another shop the car needed to have a main rear seal replaced for the oil leak the car has. ($2000) Now they could have agreed and taken our money BUT they told us it was a valve cover leak. Really cheap to fix! I would recommend these guys to everyone. I will never take my car to anyone else. - Mellody W. (5 star review on Google)

Great place to take your car. They are honest and friendly! We drive from Denver to Greeley just to take our car here because we like the place and owners so much. I highly recommend The Wrench! - Nicole B. (5 star review on Google)

Hands down, the best repair shop in Greeley! Honest, hardworking, and honest establishment. They fixed my brakes for a THIRD of the estimate that another shop gave me! Ask for Darren; he's great!!! - Verified Customer (5 star review on Google)
