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.

"The sale has successfully brought many new collectors into the market for the first time, which is fantastic news for our hobby," said Rob Myers, CEO and founder of RM Auctions.
