In 2022 drove the Z to the 66th Hillsborough Concours d'Elegance, which is the oldest Continuous Concours in the World, running every year since 1956. (Pebble Beach started a couple of years earlier, but did not hold an event in 1960 due to "scheduling conflicts") Not as big as Pebble Beach, but still lots of incredible ancient motorcars. (and Pebble Beach does not have a Japanese car class, not to mention incredibly expensive entrance fees) Judging of all Concours events in N. California is done by the San Francisco chapter of the SCCA. They do not give out judging sheets, so no one knows why anyone came in first or second etc. It is an old boys club that rationalizes their secrecy because someone might get mad about errors they made... This has caused one beautiful Z Owner (another Motorman restoration) to swear off all judged events. One wonders how many other folks this has discouraged from entering SF SCCA judged events)
However, Hillsborough does have a Japanese car class, because the wife of the organizer is Japanese! And we received 1st in Class, thanks to only 2 other cars in the class. One a modified 240Z, beautiful Z, but Concours judging rules are identical to ZCON "Stock" rules, ie. no mods. And the other car was a '93 Acura NSX, where the owner was not present when the judges came to judge.
This is a poster I use at events like this to show attendees why the 240Z was such an important vehicle in automotive history.
