Demolition Derby

Vehicles
Competitors have traditionally used full-size, American made sedans, and station wagons, especially those from the 1960s and 70s, which were larger, heavier, and had more robust frames than later full-size vehicles. The 1964-1966 Chrysler Imperial achieved near-legendary status for its crashworthiness, and is still banned from most derby events. Scrap vehicles are purchased from junkyards and private owners, usually for less than US$500, though some select (and rust-free) mid-1970s sedans, and station wagons, may go for more than $1,000. A vehicle may be patched up and re-used for several events.
With the dwindling availability of these older vehicles, smaller full-sized vehicles of the 1980s and 1990s are more frequently encountered today. A separate class of demolition derby for compact cars is increasing in popularity. Compact car events have the advantages of an abundant supply of usable vehicles, which also tend to be more mobile and thus, more entertaining to fans. Being largely front-wheel drive, their back ends can sustain considerable amounts of damage before the vehicle is immobilized. However, this increased speed, coupled with the fact that compact cars tend to be less crashworthy, makes injuries more frequent.
