Replace it with police rp and use the car's and models that were used when the fp reboot update was "taking place" and the map was temporarily on evocity. (for any of you that remember)
They had a system where you spend more time and did more things as police then you could get better cars and etc.
But make it like an actual police rp server with serious roleplay and stricter rules than ssrp otherwise it's just gonna be minges.
