Maybach Exelero: $8 million

The Exelero was designed as a one-off in 2004 by Maybach for Fulda Tires to test new tires. The car, which has 700 horsepower and a twin turbo V12 engine, was bought from Maybach in 2011 by rap artist Birdman (real name Bryan Williams) for $8 million. The car can allegedly go from 0-60mph in 4.4 seconds and has a top speed of 218mPH
