Random order of WP_Query results with highest meta value

OK, so you’re almost there. Let’s say you have this query:

$argsLoop = array(
    'post_type'      => 'cars',
    'posts_per_page' => 12,
    'paged'          => 1,
    'meta_key' => 'cars_price', 
    'orderby' => 'cars_price',
    'order' => 'DESC'
);
$cars = new WP_Query( $argsLoop );
// All you have to add is this line:
shuffle( $cars->posts );

Now you can do standard loop and the selected cars will be showed in random order.
