I know of a few very expensive rare cars that were lost in the Palisades fire, 12 friends lost their houses. There were some very rare cars there. The ones I know about in Brentwood had the time to get them out, in the Palisades fire there was no time to get them out and exit streets were gridlock.
Sadly, there has to be numerous works of arts, collectibles, cars, etc lost. Way too many days until we learn the ultimate loss.
