Floyd Mayweather has an incredible collection of cars -- mostly in white. But what if he's not feeling white? Don't worry, they come in black too. Just like when you buy a shirt and you really like it so you buy it in another color just to have it -- it's like that, just with ridiculously expensive rides. Mayweather posted a photo on Instagram with the caption, "I decided to get my black toys out tonight EWB Rolls Royce Ghost and Bentley Mulsanne".
