Couldn't you precalculate and put them in your javascript in the page
itself?
<script>
var nissancars = {{=XML(nissancars)}}
var toyotacars = {{=XML(toyotacars)}}
object.onchange="changeMake(this)"
function changeMake(carmaker){
if(carmaker.value == "nissan")
{
updateOptions(nissancars);
}
if(carmaker.value == "toyota")
{
updateOptions(toyotacars);
}
}
</script>
