I first started going to Collins Muffler about a year ago, and have to say they are great at letting you know what is wrong with your vehicle in a very timely manner as well as notifying you right away if they find anything that was not talked about before hand & always give you the price & time it will be ready....Joe the General Manager has one of the first honest mechanic shops I've found in Greeley...Thank you for all the Great work and help you did on the car guys!

I wouldn't buy a car anywhere else. Steve Monroe really finds you what you want and need.

Thank you !

This place rocks. Chino and Sean are very friendly and helpful. I had duals put on at a great price and in a timely manner. I recommended this place to all my friends. You will be satisfied with what ever service you have done there.

This place sucks! If you are interested in getting screwed then look no further than Collins Muffler! If not, STEER CLEAR! The owner is a major league a__hole!
