The record-breaking live-auction day included the highest amount for a single live auction lot — $2.7 million for a seven-night Mediterranean cruise for six couples onboard the 312-foot superyacht M/Y Whisper, plus $1.4 million for a 2024 Rolls-Royce Spectre, the automaker’s inaugural all-electric vehicle and the only one to be auctioned off in the U.S. this year.
