Each creation on this list represents a unique expression in automotive design and engineering. To clarify, we are not talking about “all show, no go” concept cars here. These whips are real and being driven. While some were the result of special orders by billionaire clientele in partnership with luxury auto manufacturers, others were handcrafted by visionaries looking to turn boyhood dreams into reality. (See #19, Paul Moller Skycar.) Either way, the 25 cars we have chosen each occupy hallowed ground as unbelievably cool, one-of-a-kind dream machines. Buckle up and enjoy the ride.
