Popular resources for finding cars priced under $500 in the United States include eBay.com and Craigslist.org. Both of these websites may be filtered by price, types of sellers and location.
To find cars for under $500 on Craigslist, select your location from the map on the home page, or allow the site to access your location by clicking Ok from the pop-up message. Next, select the city closest to the location where you want to search listings. Navigate to the For Sale section located in the middle of the page, and select Cars+Trucks and then By-Owner Only on the next page. Enter "500" in the Max-Price field in the sidebar, and click Search.
