WordPress - Get childpage links while looping all pages (Custom Loop)

PHP
1

Ok, I tried every solutions, searched Google and Codex, I can’t find the missing bit of code I need for the following scenario :

  1. Created a page (Models) that list all 1st child pages under it and display the title, links, custom fields and post thumbnail. (This work perfectly.)
  2. While looping these child pages, I need to link in each listing to all grand child of these pages.

Visual

  • Models
    [LIST]
  • Porsche 911 GT3
    [LIST]
  • Features
  • Technical Specs
  • Gallery
    [/LIST]
  • Porsche 911 GT3 RS
    [LIST]
  • Features
  • Technical Specs
  • Gallery
    [/LIST]
    […]
    [/LIST]

<ul class="list">			
<?php $pageChildren = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = ".$post->ID." AND post_type = 'page' ORDER BY menu_order", 'OBJECT');	?>
<?php if ( $pageChildren ) : foreach ( $pageChildren as $pageChild ) : setup_postdata( $pageChild ); ?>
	<li>
		<div class="left">
			<?php echo the_post_thumbnail($pageChild->ID); ?>
			<div class="hover">
				<a href="<?php echo get_permalink($pageChild->ID); ?>">Details</a> <a href="#">Request a Quote</a>
				<span class="small">MSRP: <?php echo get_post_meta($pageChild->ID,'msrp', true); ?></span>  
			</div>
		</div>
		<div class="right">
			<h5><?php echo $pageChild->post_title; ?></h5>
			<p><?php echo get_post_meta($pageChild->ID,'small-desc', true); ?></p>
			<div class="links">
				<ul>
					<li><a href="#">Features</a> </li>
					<li><a href="#">Technical Specs</a> </li>
					<li><a href="#">Gallery</a> </li>
					<li><a href="#">Compare</a> </li>
				</ul>
			</div>
		</div>
		<div class="clearfix"></div>						
	</li>
<? endforeach; endif; ?>					
</ul>

So into the div with a class of “links”, I need to list the child pages of each listing.

Any one ?
