In the last twelve years I have only missed the Historics/Motorsports reunion once - one of the perks of being a volunteer race worker with SCCA. :) Along with the GTO’s I mentioned, this past year we had race groups featuring Can-Am and Formula One cars, and there is almost always a group featuring vintage Trans-Am.
But back to the GTO - one car I see at vintage race events here pretty often belongs to a fellow here in the Bay Area. I saw it running at Monterey this year, and after looking closely at it for a few laps I realized it was the same car as the one I had selected as the wallpaper on my computer at work!
There’s a documentary on Ralph Lauren’s car collection. He loaned it out to a museum. Worth a watch for car nuts. His collection is amazing.
This is a short clip on it:
