Displaying custom post types in front end

You can do that easy on this way, just duplicate single.php and rename to single-custom-post-type-name.php like single-cars.php, same thing with archive or taxonomy, taxonomy-taxonomy-name.php or archive-taxonomy-name.php

Or you can make your query for random page, home or blog:

<?php
// The Query
$query = new WP_Query(array('post_type' => 'your-custom-post'));
query_posts( $query );

// The Loop
while ( $query->have_posts() ) : $query->the_post();  
  // your post content ( title, excerpt, thumb....)
endwhile;

// Reset Query
wp_reset_query();
?>

Good luck! 😉
