Two companies that buy and sell antique cars are AutoTrader Classics and ClassicCars.com. Both of these companies have websites where customers search for specific types of antique cars.
AutoTrader Classics lets users buy antique cars of their choice or post advertisements in hopes of selling their own antique car. As of 2015, car owners pay for one of four types of ads for the company to publicize. Ads vary by price, amount of time publicized and amount of photos of the car featured.
ClassicCars.com allows users to browse through antique cars by type, popularity, year, price and location stationed. To sell their own antique car, users post information about the car and multiple photos for an advertisement on the website.
