Description: The four Firearrow concept cars were all designed by Chrysler's legendary Virgil Exner and built by Italy's Ghia.

The two Firearrows sold at Barrett-Jackson's Scottsdale Ariz. auction are the only survivors of the set. Both -- Firearrow II and Firearrow IV -- are driveable cars, but IV was engineered as a production-ready concept. Chrysler decided not to proceed with a production version, however.
