It should be no surprise that Floyd Mayweather has cars priced well over a million bucks. What may be surprising is just how many he actually owns. 'Money' Mayweather's car collection is considered to be one of the largest out there. But that just comes with the territory of being a superstar boxer and the fact Floyd Mayweather is worth around $350 million helps. He can literally afford anything he wants and his favorite thing to buy is incredibly powerful cars.
