Maybach Exelero
In the relatively short history of ultra-luxury supercars, the Maybach Exelero ($8 million) is quite an interesting footnote. Based on the Maybach 57, this one-off coupe was created by the tiremaker Fulda to show off its latest and greatest rubber, and features a turbocharged V12 good for 700 horses and a top speed of 218. It was supposed to be purchased by the rapper Birdman, but apparently Birdman is a little bird-brained with his cash, so if you want it, it's likely yours for the taking.
