2. 1921 Helica de Leyat – $20 million
The 1921 Helica is produced by French carmaker Marcel Leyat, and it is called “The plane without wings.” Only 30 models rolled out of the plant, and de Leyat has everything collectors look on a car. It is old, extremely rare and unique in every sense of the word. Today, the Helica de Leyat in good shape costs more than $20 million.
