He won every round of the ARC one year, I think I read that in ARN not long ago.
Edit: See
here. It was in a Fiat.
"Generally, when the Fiat finished, Carr won, and it was a scenario that was played out regularly throughout his brilliant career. In his stellar 1989 season, the Canberra driver won every round of the ARC, and took the title with ease."
Another Edit: rally.com.au has him winning in a Lancia, and Lancia taking the manufacturers title. Hmm...
