Carrozzeria Ghia

Ghia initially made lightweight aluminium-bodied cars, achieving fame with the Alfa Romeo 6C 1500, winning Mille Miglia (1929). Between the world wars, Ghia designed special bodies for Alfa Romeo, Fiat, and Lancia, one of the most famous was the Fiat 508 Balilla sports coupe (1933). The factory was rebuilt at Via Tomassi Grossi, after being demolished in an air raid during World War II (1943).

After Ghia's death (1944), the company was sold to Mario Boano and Giorgio Alberti. The Ghia-Aigle subsidiary was established in Aigle, Switzerland (1948).

Following differences between Boano and the company's Naples-born chief engineer and designer Luigi Segre, Boano left the company in 1953 and ownership passed to Segre in 1954. Under the ownership of Luigi Segre, between 1953 and 1957, Giovanni Savonuzzi became Direttore Tecnico Progettazione e Produzione Carrozzerie e Stile and established Ghia as the most influential proponent of that Italian styling that came to define automobile design trends worldwide. The decade between 1953 and 1963 saw many foreign firms ordering Ghia designs, such as Volkswagen (the Karmann Ghia) and Volvo. Chrysler and its designer Virgil Exner became a close partner for 15 years, resulting in eighteen Chrysler Ghia Specials (1951–53), the K-310, the Chrysler Norseman, the Imperial Crown limousines (whose notable owners included Jackie Kennedy and Nelson Rockefeller), and others. There are even a few Ghia-bodied Ferraris. Ghia also participated in the short-lived Dual-Ghia venture. Production by Ghia was always in very low numbers, giving the company's products even greater exclusivity than those of the other Italian coachbuilders.

In June 1953, Pierre Lefaucheux, Renault's chairman, requested Carrozzeria Ghia assistance with the Renault Dauphine.

In 1953, Boano left for Fiat, the factory moved to via Agostino da Montefeltro, and Luigi Segre took over. Ghia then brought in Pietro Frua, appointing Frua as head of Ghia Design (1957–60), designing the Renault Floride. After Segre's death in 1963, Ghia was sold to Ramfis Trujillo in 1965, who in turn sold the company in 1967 to Alejandro de Tomaso, owner of a rival design house. De Tomaso never managed to run Ghia profitably and in 1970 he sold his shares to the Ford Motor Company. During this transition period, Ghia had partial involvement in the De Tomaso Pantera, a high-performance, mid-engined car using a Ford V8.

From then on, the Ghia studios were an integral part of Ford of Europe's styling operation – producing mostly concept cars although some production models were styled by the firm – the most notable being the Ford Fiesta Mk1 in 1976, which was penned by Ghia's Tom Tjaarda. Aside from this, the most publicly visible sign of Ford's ownership of Ghia has been its use of the name to denote the luxury trim level of its European models for many years (below).
