One of the most amazing automobile prototypes of the 1930's was the 1938 Phantom Corsair. This very unusual six-passenger coupe was jointly designed by Rust Heinz. Heinz planned to put the Phantom Corsair (which cost approximately $24,000 to produce in 1938 - approximately $300,000 in 2005 dollars) into limited production at an estimated selling price of $12,500. His death, however, shortly after the car was completed, ended those plans.
