What is the most money ever spent on a car?

There's no single definitive answer to the question of the most money ever spent on a car, because the value can be subjective and depend on what's included (e.g., the car itself versus the entire transaction including commissions and related purchases). Also, private sales aren't always publicly known.

However, cars that have sold for extraordinarily high prices at auction, often exceeding $40 million, are frequently cited as contenders. These are typically extremely rare classic cars, often one-of-a-kind prototypes or historically significant vehicles. The exact price and the car itself can change depending on the auction and time frame. There's always a possibility a private sale could have surpassed these public auction records.
