Mayweather brought Obi Okeke, who co-owns Fusion Luxury Motors in Chatsworth, California with him to Miami to put the deal together.

Okeke says he has sold four Bugattis to the boxer including one with 2,200 miles he traded in for his latest purchase, the convertible Vitesse that Okeke says is one of only 44 ever made. The black and orange color scheme and interior is one-of-a-kind, he said.

"You can't go and order one," Okeke said Tuesday after a flight home from Miami.

Bugatti's website says the car reaches speeds of 254 mph (408.8 km) and accelerates from zero to 62 mph (100 km) in 2.6 seconds and has 1,200 horsepower. The site also says the car is sold out.

Bugatti has built and sold 450 Veyron models between 2006 and 2015 and 150 are convertibles like the one Mayweather bought Monday, Okeke said.

Okeke said he and others followed Mayweather out of the Miami dealership's lot as the boxer drove away, driving in a "progressive manner," on a Florida freeway, he said diplomatically.

He said Mayweather is already eyeing his next possible purchase, a USD 3.2 million Pagani Huayra that's been flown to Okeke's California showroom. Okeke said he's sold Mayweather more than 39 cars, including the four Bugattis.
