What is the most expensive car of

The title of "most expensive car" is fluid and depends on several factors, including the year, condition, and any unique features of the vehicle. There's no single definitive answer. However, some contenders for the title of most expensive car *ever sold* include various ultra-rare classic cars and one-off hypercars, often fetching tens or even hundreds of millions of dollars at auction.

To get a more precise answer, you need to specify what you mean by "most expensive":

* Most expensive ever sold at auction? This changes frequently as rare cars come up for sale.

* Most expensive new car? This typically refers to limited-production hypercars with extremely high price tags.

* Most expensive car in a specific category (e.g., classic cars, electric cars)? This narrows the field considerably.

Once you clarify your question, a more specific and helpful answer can be provided.
