Which billionaire drives a Volkswagen hatchback?
Mark Zuckerberg is worth somewhere between $13 billion and $20 billion, and is the second youngest billionaire in the world (after his old college roommate). He could afford to drive any car in the world, or own a fleet of the finest. However, the Wall Street Journal has revealed that he drives a black Volkswagen GTI.
And he's not the only multi-millionaire who is careful with his money.%VIRTUAL-SkimlinksPromo%
ZuckerbergZuckerberg, the article claimed, gave his friends socks for Christmas - featuring a picture of his dog. He also made headlines when he chose to get married in his back garden with fewer than 100 guests and no wedding cake.
It may seem odd to outsiders to see someone choose such simple things when they can afford the best, but for Zuckerberg, these appear to be the things he likes, so why go overboard?
And he's not the only multi-millionaire who lives a surprisingly thrifty life.
Thrifty habitsPerhaps the billionaire best-known for his money-saving ways is Warren Buffett, the investment guru who is worth almost $60 billion. He still lives in the modest property in Nebraska he bought more than 50 years ago for just over $30,000, and favours hamburgers and soft drinks over anything more expensive.
Ingvar Kamprad, the founder of Ikea, is another billionaire with thrifty ways. He uses his own furniture, drives a 15-year-old Volvo, eats at local diners and flies economy class.
Azim Premji, an Indian tycoon who is worth around $12.7 billion, drove a Ford Escort for eight years before upgrading to a Toyota Corolla. He is also said to walk to work, stay at budget hotels when travelling on business, and fly economy class.
Closer to home, Phone 4U billionaire John Caudwell told Forbes magazine that he cuts his own hair and buys his suits off the rack at M&S, adding: "I don't need to spend money to bolster my own esteem". He does, however, own an enormous mansion in Mayfair and a Bentley, so he's enjoying some of the comforts of wealth.
We also recently reported on David Ashcroft, the 46-year-old furniture restorer from Liverpool who gained a reputation for being the country's thriftiest millionaire lottery winner. He still lives with his parents in a modest terraced house, and his most extravagant purchases in the 16 years since his win have been double glazing and a new work van.
