If you are wondering what Filter Everything is, take a look under vehicles in the main navigation. See all those options In the left column. That is what the filter everything plugin does. You can filter results on that page by Make, Model, Price, Colour and Mileage.
This plugin works with WooCommerce, ACF and other much used plugins to help you create filtering options for products, posts and many other things.
Have a play with the filters.
