    new id = GetPlayerVehicleID(playerid);
    new vehicleid = VehicleID[id];
    strmid(VehicleNumberPlate[id], inputtext, 0, sizeof(VehicleNumberPlate[]), 255);
    SaveVehicle(id);
    SetVehicleNumberPlate(id, inputtext);
    SetVehicleToRespawn(vehicleid);
    new msg[128];
    format(msg, sizeof(msg), "You have changed vehicle number plate to %s", inputtext);
    SendClientMessage(playerid, -1, msg);
    return 1;
}

Hope this will work
