the website in question is right here I’m trying to generate a CSS dropdown, however no such option is available in wp_list_pages(), I also won’t be able to get the desired effect using WP Menus in the appearance menu (I used this method to generate my footer links)
This is ideal:

I know how to generate the menu, I just don’t know how to get it under the “cars” menu without a hack javascript solution.
The ideal solution involves targeting the list item by the template name “Car Showcase” and allowing me to generate PHP/HTML (The code needed to make the dropdown) after it. Does this make sense to everyone?
The actual way to create custom HTML for WordPress menu is to create a Walker
