Floyd 'Money' Mayweather certainly lived up to his nickname as he expanded his collection of cars with his most expensive purchase to date. Floyd Mayweather continued to live up to his 'Money' nickname - by buying the flashiest car on the market. The pound-for-pound best fighter in the world posed with his brand new buy, a Koenigsegg CCXR Trevita 'Hyper Car' in a plush garage in America. Koenigsegg have produced just two Trevita cars and Mayweather has his hands on the second. It is also the only one in the United States.

The exclusive manufacturer is branded as the 'ultra automobile manufacturer for the super-rich' - perfectly fitting Mayweather's billing as the most wealthy sportsman on the planet. Writing on Instagram, he said: "My new 4.8 Million dollar car. $4,800,000.00 Koenigsegg CCXR Trevita supercar."

Mayweather drove the car - while his entourage droves some of his others - to the Mayweather Boxing Club for his open media workout on Wednesday.

Mayweather is currently preparing for the 49th - and said to be final fight of his career, when he takes on Andre Berto on September 12th at the MGM Grand in Las Vegas.

Mayweather took home $300 million for his role in the May 2nd super-fight with Manny Pacquiao earlier this year - the fight branded the richest in the history of boxing.
