There are a number of different websites where someone can buy a Geo Metro car, including sites like Cars.com and Auto Trader. Used cars can also be purchased through eBay and Craigslist, as long as users know how to narrow a search.
Cars.com is one site that allows users to narrow their search to their location. The search engine on this site allows for a zip code search. Once this search is done, it shows the Geo Metro cars that are available for sale and also enables users to contact local dealers. The website page also details the year of the make and some of the most prominent features. Cars for Sale has a similar search engine, though it has more functionality and can be used to narrow the search and aim for a specific price range.
Autotrader has a similar search engine to the other sites, though it also makes it very clear who to contact once a preliminary search has been done for all Geo Metros in a user's area. Mileage of a used car is prominently displayed, and each seller is given a small section on the ad pages to make their pitch to users about the Geo Metros they are selling.
