Yeah, Ed has specific entry information going as far back as 1999 on his site. Additionally, he has a comparison between 1980 and 2000 showing the change (in adjusted dollars) between those 2 years.
I'm looking for specific entry cost for the 6 or 7 years.
I know Ed, the keeper of all things good regarding rally, has this information somewhere. He has the biggest fileserver out there!
