List posts by Taxonomy

I need a little complex loop finished

Here is the site I am working on.

http://prothane.com/complete_kits.php. It has lots charts. To make things easier for admin, I need to find a solution so admin just enter data like post and charts become ready so thought to use custom post type, taxonomy.

I made this page as custom post type “Total Kits” – “total-kits”

The titles in red are Taxonomy

and data under red titles are posts with custom fields – no title – no post content.. just custom fields will be listed

So far I am able to get all things

but just not getting posts listed under a taxonomy.. thing is that I need to list Taxonomy and posts underthat

like “Import & Domestic Cars” is taxonomy and post under that should be like this

Import & Domestic Cars
>> post 1
>> post 2

taxonomies can be any number of ..

Following is the code.. I am able to list taxonomies for this custom post type

<?php $args = array( 'post_type' => 'total-kits', 'posts_per_page' => 10 );
$loop = new WP_Query( $args );

while ( $loop->have_posts() ) : $loop->the_post();
$cat = get_the_term_list( $post->ID, 'totalkits_cat', '', ' ', '' );
echo $cat .'<br />';

endwhile; ?>
