Used automobile trailers are available for sale online at CommercialTruckTrader.com and eBay.com, as of April 2015. Most of the Commercial Truck Trader sellers are dealers, but there are a few private sellers.
EBay's selection includes open and enclosed trailers of various dimensions. One of the longer trailers available is 45 feet long, and the smaller ones are shorter than 10 feet. Users can refine the results by length, make hitch type and carrying capacity.
Commercial Truck Trader's selection is similar to eBay's and includes simple trailers with no floor — just ramps that act as the floor. There are many types of commercial and residential car trailers, including several trailers that haul multiple cars.
