When a C7 has to compete against everything Europe can throw at it from the fastest Renault hatchback to the crazy Ariel Atom 3.5R, it's a real shame the 2015 Z06 is not out yet.
World's coolest superyachts. Biggest, most expensive: Azzam. With a price tag of $627 million and a length of 590 feet, Azzam is bigger than a U.S. Navy destroyer. Not much is known about the world's longest and most expensive yacht.
Luxury yacht prices, like the yachts themselves, differ enormously. According to 2014 sales data, the average yacht price for a second-hand yacht for sale is â¬7.9 million ($8.4 million), but prices of super yachts can start at around $1.5 million for a small or older yacht and rise to a $600 million, which is how much Azzam, the largest yacht in the world at 590 feet cost to build.
