My son and I saw the adverts for this at Bathurst this year.There is also another group out there called "sideways action" who do something similar.They have a website
www.sidewaysaction.com.au not sure how much they charge as theirs is more rallying.
Son did one of these type of drives when he was in the UK for a holiday this year {it was our 21st b/day present to him} and he said he had a blast!After some initial instruction with the instructor beside him,he was let loose on his own.The guy who ran it reckoned my son was a natural and would do well at rallying.And considering he was in a Ford Focus a car he's never driven before,he did ok.Bet he wished he had his Lancer with him.
