What would you do if you suddenly had the money to spend on all kind of frivolous things? Would you go shopping for the world's most expensive car or take sail around the world? Would you travel to the most expensive city on Earth? Or maybe treat a date to a $1,000 dinner? Whatever your choice, here is a little glimpse into what being a millionaire would let you do.

Most Expensive Car

The world's most expensive car has been around for over 85 years. A 12.7 liter cylinder engine, 300 hp, and a hood that reaches five feet high, make this the most impressive car ever designed. Built in the 1920's and 30's by Ettore Bugatti, who used part of a 16-cylinder aircraft engine, the Bugatti Type 41 Royale Kellner Coach is one of a kind. So special, in fact, that only six were built. Of those, two stayed with the Bugatti family until one of them was finally sold in 1987. Since then, it changed hands a few times, and it was recently bought in auction by an anonymous millionaire for the hefty price tag of $10 million.

Most Expensive Cruise

Welcome to the Queen Mary 2, the world's largest and most expensive cruise ship ever built. Owned by Cunard, it hit the waters in January 2004 and made, literally, quite a splash. A Todd English restaurant, a Canyon Ranch's spa, the largest ballroom on water, and a cabaret are just a few of the amenities found on board. Add to that a planetarium, a wine tasting seminar, a basketball court, and a playing field, and you're beginning to get the idea of what the Queen Mary 2 is all about. The cruise's top offer is the 121 night around-the-world voyage, which costs a lavish $480,000.

Most Expensive City

Tokyo has ranked first for years as the world's most expensive city. In a place where rents easily reach $8,000 a month and a three-month security deposit is required, you're left to wonder… does anybody but a millionaire live there? Apartments come without refrigerators, so you'll have to buy your own for about $900. No phone line either, which costs up to $700 to set up (depending where you live). Going out? Expect to pay $5 for either a coffee or a small beer, and an average $15 for a serving of sushi. Or stay in and order a pizza for $25. A microwave will set you back almost $600, same as a washing machine. Got a cold? Your average over-the-counter cold medicine runs about $15.
