change your callback 'OnPlayerEnterVehicle' from this

Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
	new string[128];
	format(string, sizeof(string), "You are entering vehicle %i",vehicleid);
	{
	if(GetVehicleModel(GetPlayerVehicleID(playerid)) == 487 && team[playerid] != 6);
	RemovePlayerFromVehicle(playerid); //Indent
	SendClientMessage(playerid, YELLOW, "Restricted to S.T.A.R.S. !!"); 
	} 
	return 1; 
}

to this

Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
	new string[128];
	format(string, sizeof(string), "You are entering vehicle %i",vehicleid);
	if(GetVehicleModel(GetPlayerVehicleID(playerid)) == 487 && (team[playerid] !== 6)
	{
		RemovePlayerFromVehicle(playerid); //Indent
		SendClientMessage(playerid, YELLOW, "Restricted to S.T.A.R.S. !!");
	}
	return 1;
}

Make backup always its not tested... i also would suggest to use OnPlayerStateChange and not OnPlayerEnterVehicle

EDIT: I edited a code.. there was a missing character and it wouldn't work, try now.
