23. Aston Martin Vulcan

Price: $2.3 million
The Aston Martin Vulcan is one of the rarest hypercars to be built. A grand total of 24 were built, and the car was produced for track-only driving. It has been reported however, that some of the cars were converted for street use later on.
The Vulcan is powered by a naturally aspirated 7.0-liter V-12 engine, making 800hp.
You could have purchased an Aston Martin Vulcan for $2.3 million USD when the car was originally advertised.
