The sale shows that, with markets at all-time highs, the wealthy continue to pour money into top collectibles—especially art and cars. The sale was also the first major collectible car auction in Manhattan in a decade.
The bidders came from 17 countries, showing that the collectible car market—like the art market—has become far more global in recent years.
