The price difference between Citroen WRC( to buy £500,000,-)and C4 rallycross car(to buy less than £ 150,00,-)is about £350,000,-. The main difference is one more seat. How can one seat cost £350.000,- Why is this this? Info is from Hansen. It looks some body is making a lot of money. I would not do it. I like too much of our sport.
