Remember that Berkshire Hathaway (BRK.A) head Warren Buffett, the man behind the billions, isn't your run-of-the-mill mega-rich investor.
Buffett loves junk food and eats just about whatever he wants.
Buffett's Omaha home is the only one he lives in. He paid $31,500 for the five-bedroom in 1958, or about $250,000 in today's dollars. Buffett's house is now worth as much as $652,619, according to Realtor.com. Buffett called the house the third-best investment he's ever made.
Buffett has donated about $25 billion to charity in his life and plans to donate 99% of his wealth before his death. He's started a pledge to get other mega-rich business titans to join him. The Giving Pledge has earned signatures from 137 ultra-wealthy names.
Warren Buffett is notoriously frugal, but he can afford any car he wants. He traded in a General Motors 2006 Cadillac DTS to purchase a 2014 Cadillac XTS in the summer of 2014.
