Search Exclusion Tagging System
Add an "excluded from search" feature to slim down irrelevant results. For example, a tagging system. That way, when you search for any car within your budget, but know you don't want a Toyota, you aren't spammed with pages and pages of Toyota RAV4's before you can get to the good stuff.

This can be done with negative keywords. Simply put hyphens before your keywords or key phrases like -toyota -“leather seats” to remove any listings with those words or phrases.

Doesn't work to exclude exterior colors, eg -gray -grey

Searching for Toyota Prius, this works to exclude the "v" and "c" models but not the "plug-in", using -plug -"plug-in" -"Plug-In"
