Simple nice but if you want the wording: Model: in front of the numbers you have to add this:

this is for the includes/ modules/ featured_products.php
PHP Code:
$products_price . '<br />' . 'Model:&nbsp;' . $featured_products->fields['products_model']); 
this is for the includes/ modules/ new_products.php
PHP Code:
$products_price . '<br />' . 'Model:&nbsp;' . $new_products->fields['products_model']);
