Possibly not all that amazing Michael, considering they probably shared a mutual professional dislike. Both attempting to dominate the locals and stick it up the visitors at Tasman level, both attempting to be competitive in the US, both designing and building their own cars. As you know from racing, you can get along with some folk but on-track it can be pretty gritty when they come into your immediate space. It may have been only later that they have both let the competitive spirit subside, and the long-suppressed acknowledgement of appreciation flow, however begrudgingly. Anyway, I would love to have cast an ear over that conversation. Two giants from our end of the globe.
Edit : This gets mentioned in that excellent Derek Kneller interview on the next page...
