You can sell a new or used van online through specialty automotive classifieds such as Autotrader and through general classifieds such as Craigslist. Auction sites such as eBay can also be used to sell vans to both local and long distance buyers.
Autotrader offers several different tiers of paid advertising as of March 2015, with the major differences between the options being the duration of the ad on the site, the number of photos the seller can include in the post and some special features such as premiere placement on the site. All advertising options feature the site's money back guarantee, which allows the user to initiate a refund process if they are unhappy with the services received. The site also offers a guided selling experience in which a sales associate works with the seller to create the ad and ensure optimal performance until the van is sold.
Alternately, Craigslist allows users to create ads on the site for free, though it does not have any services to aid users with this process. Users can include up to 25 pictures of the van in each posting, as well as a written description. Listings are automatically taken off the site after seven days unless the user renews the posting.
