what do you want, if you want that you get a message if you are in the vehicle with the vehicleid 522, you need to remove the '!'
But I think you wanted to send this message if the player is in this vehiclemodel

pawn Код:

new VModel = GetVehicleModel(GetPlayerVehicleID(playerid));
                if(VModel == 522)
                {
                     SendClientMessage(playerid, COLOR_RED, ".........................................)");
                }
