My question involves vehicle registration or title in the state of: New York

Currently a resident of Colorado. My wife's car was purchased and registered in New York 16 years ago. The car has been paid off for 10+ years and we cannot find the title. It was co-signed by her father but he doesn't have it. We attempted to get a copy of the title from the State of New York but they no longer have the title. The goal is to simply donate the car to charity. How do I go about getting a copy or even a new title for the car? Any ideas or help would be appreciated.
