You will not see Warren Buffett driving around in one of these....
Perhaps the most expensive and rarest of all super powerful and super expensive cars is the Koenigsegg CCXR which is manufactured in Sweden by a team of beautiful blond builders in bikinis. Only six pieces of the car have been sold at a sticker price of (hold your breath) $1,900,000.00 (yes, that is almost $2 million dollars).
A serious contender (if it comes do price and speed) of Tesla Motors. Swedish Koenigsegg states it is the fastest green (biofuel) super car in the world capable of achieving a top speed of 250 miles an hour (any faster would make it an airplane). So who buys a $1.9 million car? Well, the people that sit on one of the largest oil reserves in the world, the Royal Family of Qatar. The simply flew over the car from Qatar to London for the summer. The Koenigsegg CCXR was last spotted in front of Harrods (which happens to be owned by the Royal Family of Qatar as well).
The owner of this car sure doesn't seem to worry about Compound Interest any longer... I guess it is all about striking a balance.
