Demolition derby cars are available for purchase through Festivals-and-shows.com and DemoDerbyJunk.com. In addition, local newspapers often carry classified ads for demolition derby cars, sometimes posting these ads online. Demolition derby is a motor sport in which drivers smash older cars into each other; the last functioning car is the winner.
Festivals-and-shows.com advertises used trucks, cars and station wagons for demolition derby purposes. Available vehicle models range in age from the 1970s to the early 2000s. Some cars have roll cages installed, while others require significant mechanical work. DemoDerbyJunk's cars tend to date back to the 1970s, and the site also features "rolling shells," or cars with no working engines. Similar offerings are found on local classified ad sites, such as Pennswoods.net.
