If you're really balling, you know that submarines are the only way to travel in style in 2012. That being said the Royal Norwegian Navy is offering the Olavsvern Naval Base, a secret, mountainside submarine base which NATO spent $494 million building, for sale for an incredibly reduced price of $17.3 million. With an above-ground space measuring in at 13,500 square meters with another 25,000-square meters of space inside of the mountain, the base is the perfect spot to store your submarine while you're not, you know, using it. The indoor space includes offices, a dry dock for submarines and boats, and an awesome system of tunnels.
