World's Most Expensive Cars

Hate the smell of exhaust or the skunk you just passed on the highway? If you buy the Maybach 62 Zeppelin, your nose will never have to suffer again. The car comes with a built-in, illuminated atomizer that gently diffuses the fragrance of your choice throughout the cabin.

Granted, that peace of mind will cost you--to the tune of $506,500. But that's the low end when looking at the limits of what money can buy at the dealership. For a whopping $1.8 million you can get the Cinque Roadster, which features a stunning 678 horsepower V12 engine, carbon fiber racing seats, a titanium suspension and a 0-60 mph time of 3.3 seconds.
