There's no single definitive answer to the "most expensive car" question, as prices can fluctuate wildly based on factors like customization, rarity, and the specific buyer and seller. However, cars routinely fetching prices in the tens or even hundreds of millions of dollars at auctions are typically one-of-a-kind classic or highly customized modern vehicles.
Therefore, there's no consistently "most expensive car." News reports will periodically declare a certain car the most expensive *at that time*, but that record is frequently broken.
