Folkrace is an inexpensive, entry level type of rallycross. To maintain its inexpensive nature, there is a rule on price. The races are run in old standard cars, but almost anything goes, as long as they meet certain minimum safety regulations. The car should not cost more than about USD 1000 to rule out any unfair advantage, even if it benefits those who are mechanically skilled and thus can fix their own car. The price rule is enforced using a bidding system. After a race, all participants can exercise their right to place a bid on any of the other cars entered in the race. The owner of the car has no choice but to sell or else lose their license. This type of system eliminates the motivation for sinking extensive amounts of work and money into a car.
