[Scenario]

I see the problem, try this:

pawn 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;
}
