The 1960 Plymouth XNR will cross the block next month at the RM Auction in Monterey, Calif. The one-of-a-kind sports car was penned by Chrysler design guru Virgil Exner, who always hoped Chrysler would include a roadster in its lineup. The XNR featured a powerful six-cylinder engine that pumped out 250 horses and gave the XNR a top of speed of 150 mph.
Ultimately, the project never got the green light, and the XNR was shipped back to Carrozzeria Ghia in Italy, where it was built.
From there, the car's story gets more interesting. A series of owners bought it in the '60s, and it wound up in the Shah of Iran's garage.
