All Craigslist sites have a section of classified ads for used cars posted by owners and dealers. The user accesses this section by clicking on the "cars+trucks" link under the "for sale" heading on the user's local Craigslist site. Click on the "By-owner Only" link to filter out dealer ads.
The listings consist of a car's picture with a caption describing the type of car for sale and the price suggested by the owner. Clicking on a listing directs the user to a longer description of the car for sale, more pictures of the car and contact information. The amount of cars listed depends on how populated the area served by the site is.
