Are you looking for something like this?

pawn Код:

CMD:gunstorage(playerid, params[])
{
    new vehicleid
    if(ssanf(params, "d", vehicleid))
        return 1;

    if(GetVehicleModel(vehicleid) != 519)
        return 1;

    new Float:Pos[3];
    GetVehiclePos(vehicleid, Pos[0], Pos[1], Pos[2]);
    if(IsPlayerInRangeOfPoint(playerid, 5.0, Pos[0], Pos[1], Pos[2]))
    {
        // do something here
    }
    return 1;
}

This is an example where you have to enter vehicle's ID in the command. You could run a loop to find out is player standing near any shamal.
