Colorado Revised Statutes Title 42. Vehicles and Traffic § 42-9-107. Used, reconditioned, or rebuilt parts

The motor vehicle repair facility shall specify in the original estimate whether any parts to be installed are new original equipment manufacturer, new nonoriginal equipment manufacturer, used, reconditioned, or rebuilt and then shall obtain the consent of the customer before any new original equipment manufacturer, new nonoriginal equipment manufacturer, used, reconditioned, or rebuilt parts are installed in the motor vehicle. If such consent is oral, the motor vehicle repair facility shall make a record of such consent on the work order and shall include the date, time, and manner of consent. The telephone number called, if any, and the name of the person giving and receiving the consent, if different than the original customer, shall be recorded on the work order. The motor vehicle repair facility shall adjust the original estimate for new parts to reflect the altered cost if used, reconditioned, or rebuilt parts are authorized and installed.
