1. Go to

Code:

public OnPlayerStateChange(playerid, newstate, oldstate)

add this:

Code:

if(newcar == MYOLDCAR || newcar == MYOLDCAR || newcar == MYOLDCAR)
		{
		    if(PlayerInfo[playerid][pMember] == FACTIONID || PlayerInfo[playerid][pLeader] == FACTIONID){ }
		    else
		    {
		        SendClientMessage(playerid,COLOR_LIGHTRED,"   You don't have keys of this vehicle !");
		        RemovePlayerFromVehicle(playerid);
		    }
		}

How to find oldcar ? Enter in vehicle then type /oldcar

2. Remake

Code:

public IsACopCar

( remake oldcar's from all LSPD vehicles )

3. If you make the point 2 (2. Remake public IsACopCar ( remake oldcar's from all LSPD vehicles ) ) this will be solved.
