The title of "world's most expensive vehicle" is fluid and depends on various factors, including the vehicle's condition, customization, and who's selling it. There's no single definitive answer. However, frequently cited contenders for the title include various one-of-a-kind, bespoke creations and extremely rare classic cars. Their prices are often not publicly disclosed, or are sold privately.
Therefore, there's no universally agreed-upon answer. You'll see different sources claiming different vehicles depending on the year and the specific sale in question.
