The Pininfarina-styled 308 GTB was introduced at the Paris Motor Show in 1975 as a supplement to the odd Bertone-shaped Dino 308 GT4 and a replacement for the 246 Dino. Unlike the plain 2+2 GT4, the GTB was a 2-seater with aggressive lines, and has been called one of the most beautiful of all Ferraris. The targa topped 308GTS was made famous on the Magnum P.I. television show.
One notable aspect of the 1975 308 GTB was its fiberglass bodywork. Although still built by Carrozzeria Scaglietti, the 308's shell was entirely made of fiberglass. This lasted through June, 1977, when the 308 was switched back to steel. When the body was switched back to steel, seven bodies were hand hammered, six red convertables and one white hardtop.
