Mayweather shared the moment on social media, writing "A Special Gift For My Sister-Just Because!" The luxury vehicle costs around $186,200 and represents the best of what Mercedes-Benz has to offer.
The gift comes as some people question Mayweather's finances. But the boxer, known as "Money," keeps showing he's got plenty to spare. He recently flew to Honduras on his private Gulfstream jet, worth about $50 million.
"The natural beauty and hospitality in Honduras are truly amazing,"Mayweather said after visiting the Bay Islands.
Mayweather's always been known for his flashy lifestyle. He's undefeated in the ring and seems to be winning outside of it too. His business ventures include real estate investments and exhibition boxing matches.
The Mercedes-Benz S63 E Performance combines luxury and power. It's a hybrid car, mixing traditional engine power with electric performance. Most of these cars are made in Germany.
Mayweather's gift to his sister and his travels show he's still living large. He's proving that family comes first and that he's got the cash to back up his "Money" nickname.
