There was a time when you could get a police car to race in Need for Speed Payback. Now it's time to get it for free ($0) and without any searching on the map.
In order to get a free police car, you need a simple "Frosty Mod Manager" tool that works with the NFS Payback game. And the car itself is installed as a mod "AbandonedPoliceCrownVic.fbmod", and then it is selected from the row to the racing car dealership.
