List in the sidebar list of Wordpress Taxonomies

Use get_term_by() to search for Ford ID and wp_list_categories() to list the child terms. If the taxonomy is not category change in the example by the appropriate name:

<ul>
<?php 
    $parent = get_term_by( 'name', 'Ford', 'category' );
    wp_list_categories( array(
        'childof' => $parent->term_id,
        'taxonomy' => 'category',
    ) );
?> 
</ul>
