When was the last time you saw a house for sale that came with a car collection? CNBC has revealed that a massive 38,000-square-foot home in Bel Air, California is now for sale. The price tag? A whopping $250 million. With this price, it becomes the most expensive house on the market, beating out the $195 million home in Manalapan, Florida. What do you get with this house? How about "12 bedrooms, 21 bathrooms, three kitchens, six bars, a massage room and spa, fitness center, two wine-champagne cellars," a pool with a 20-foot TV, bowling alley, helipad and a $30 million car collection. Why? Because why not.

"People spend two weeks a year on a yacht, but they live in a house. I wanted this to be the ultimate megayacht, but on land." CNBC reports that the real estate brokers state it will set the records for being the most expensive home ever listed, as well as the most expensive single home ever sold in the United States.
