Which of the Most Expensive Things in the World Would You Buy?

4. Antilia, Mumbai: $2 billion

Large, luxurious homes are expensive everywhere, but in sought-after areas, they can become insanely pricey. That explains why Antilia, located in crowded Mumbai, is the most expensive private residence in the world. The home of Indian billionaire Mukesh Ambani, the 27-story building, boasts over-the-top amenities, including an 80-seat theater, a 168-car garage, a ballroom, spa, and luxurious terraced gardens. Oh, and three helipads in case two just isn't enough. In 2014 the skyscraper-mansion is valued at around $2 billion.
