21: Lykan HyperSport
There are dozens of rare one-off exotic sports cars in the world, and every so often we get to see one. The Lykan HyperSport is a beautiful exotic car built by a company in the United Arab Emirates (via Ranker).

It was designed with help from Italian engineers, which is why it has a lot of Ferrari flavoring. The car never went into mass production, and there are only a few examples still on the road today.
