Its just a full pack of the NCPD vehicles in the game. They are all present in the mod but you can just add one only if you want with the CET commands.

i attached with the file a TXT file with all the commands to write in CET for having the vehicles for FREE spawnable as your own vehicles. You just need to do it once and they will stay FOREVER in your summonables cars.

They mostly dont have logos in your summonable hud but you will find easily by their names, only the Apollo bike (Police bike) have a logo but look at thoses apollo bikes names to find it.

Drop the R6 file in / R6 / TWEAKS  and put the commands lines in Cyber Engine Tweaks for having them summonable forever in your classic car spawner hud.

Here is the lines to add them :  

POLICE CHEVALIER EMPEROR: Game.GetVehicleSystem():EnablePlayerVehicle('Vehicle.v_standard3_chevalier_emperor_police', true, false) 
POLICE ARCHER HELLA: Game.GetVehicleSystem():EnablePlayerVehicle('Vehicle.v_standard2_archer_hella_police', true, false)
POLICE VILLEFORT CORTES: Game.GetVehicleSystem():EnablePlayerVehicle('Vehicle.v_standard2_villefort_cortes_police', true, false)
POLICE HELLHOUND MAN O WAR : Game.GetVehicleSystem():EnablePlayerVehicle('Vehicle.v_standard3_militech_hellhound_police', true, false)
