Car trailers are divided into two classes: open and enclosed. These trailers and trailer beds are used to transport race, performance and show vehicles to tracks, stadiums, convention halls, and fairgrounds. Open trailers are basically a flatbed with the ability to attach a vehicle to the bed. Enclosed trailers have walls and doors, and generally accomodate more expensive vehicles that require protection from the elements. Both new and used car trailers are for sale on RacingJunk.com.
