For the first time, Ferrari fanatic James Glickenhaus will publicly display both of his one-off Ferrari creations, the Ferrari P 4/5 by Pininfarina and the P 4/5 Competizione. Glickenhaus, who is widely regarded as one of the most prolific car collectors of the past few decades, will show the cars side-by-side at The Quail, a motor-sports gathering in Carmel, California that runs alongside the Pebble Beach Concours d'Elegance. 

Both cars are one-off creations, commissioned by Glickenhaus and created by an elite team of engineers and designers, that are loosely modeled after iconic racing Ferraris. According to Glickenhaus, he has been offered in excess of $40 million for each car! They will officially go on display on August 16, 2013.
