It's wood-trimmed interior is styled after the classic boats that ply Monaco's harbor, and the car has a price tag on par with many of those: $650,000. Only 15 will be built, but don't worry if you miss out on that batch, a more powerful, all-wheel-drive, supercharged hybrid version is reportedly in the works. (Montecarlo Automobile)
