Marker off-set on Google Map API v3

For v3, this is how I accomplished it:

var image = new google.maps.MarkerImage("images/car1.png",
    new google.maps.Size(60, 60),
    new google.maps.Point(0,0),
    new google.maps.Point(30, 30)
);

//ADD MARKER AT EACH POINT
var marker = new google.maps.Marker();
marker.setPosition(new_point);
marker.setIcon(image);
marker.setZIndex(0);
marker.setMap(map);
