Have the price for the cars dropped? When I was racing in bilcross ~15 years ago the price for a car was 9000 NOK. You can also bid on any car that have been in the race, not only the winners and you cannot refuse to sell. Personal safety equipment is not part of the sale. Bid is a fixed price and if several bids on the same car they draw one of the bids on random. It is tons of fun racing and safe even if you get in a heat with many who have never raced before

Sweden and Finland do also have the same, is called folkrace there
