Floyd "Money" Mayweather stood up to his nickname when he added only the fastest car in the world and definitely his most expensive car so far. The arguably best boxer of his generation posted a photo of his latest toy that cost only $4.8 million.

The athlete posed on the hood of his "hypercar" and captioned it: "My new 4.8 Million dollar car." The caption also included the description of the car saying that there are only 2 of its kind in the world and that it is the only one that has USA specs.

The Koenigsegg CCXR Trevita is of Swedish origin and its name means "three whites". It is interesting to note that the owner of the second Trevita is only Paris Hilton's boyfriend. The Trevita is indeed the car of the super rich.

Although the elite athlete could have spent his millions for something else, it doesn't really matter for someone considered by Forbes the highest paid celebrity, who recently earned $300 million last May.

Floyd's car collection demonstrates how wealthy he is by being a five-division world champion. There is no super car model that he doesn't own, Autoevolution said. He happens to be the filthy rich guy who loves cars so much he gives them as gifts.

Earlier this month, he gifted his protégé Ashley Theopane with a Chrysler 300 in appreciation of his dream to someday become the world's best boxer like him.

Theopane was training in the Mayweather gym when Floyd decided to offer the former with the best training opportunities in the hopes that he would become the best in his field.

Last February, Floyd also gave his daughter a $400k Rolls Royce so that she can "ride in style".

It may be entertaining to see Floyd flaunting all his riches, but an article in Yahoo said that his show might be nearing its end as he decides to make his September fight with Berto his last.
