Built on the Fiat 1500 platform, the 1500 GT Ghia had a 1.5L straight four. Top speed was over 100mph, thanks to an aerodynamic shape and light weight. The Fiat 1500GT was bodied by Ghia and produced from 1962 through 1967 with a total of 925 figures, among them one Barchetta in 1966 nicknamed "Avenger" (see photos below) were produced. (The total number is an estimate). The car had a monocoque body and a four-cylinder Fiat engine that produced nearly 85 hp. (conceptcarz.com)
