[Threshold]

This should work for you, basically your 'strcmp' function was using the cell length parameter, which does not equal 20 in this case... I won't explain it now, but research it a little and you'll understand.

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)

    new vid;
    new factionrequired[5] = "None";
    vid = GetVehicleModel(vehicleid);
