Pininfarina is an Italian design house tha is the Versace of auto design. They have designed many of the worlds most beautifull cars including most Ferraris, allot of Fiat and Alfa sports cars. They are still an active company and not only design beautifully sculpted autos but they now design fine pens, luggage and stationary accesories.
Other famous Italian design houses include Bertone and Italdesign.
Our beloved Fiat 124 Spider were masterfully sculpted by American born designer Tom Tjaarda commisioned by Pininfarina.The 124 Spider design was based on the prototype Corvette Rondine (swallow) and a Ferrari (cant remember the model number). The major design carry over from these two cars was the swallow shapped rear deck, kind of a mild finn look as well as the side profile. Apparently the front end was a little dificult to sculp because of the space limitations in the 124 short wheel base chasis.
The Pininfarina badged spiders were finaly discontinued in 1885 to make room for Pininfarinas latest body/chasis it would need to produce, the Cadillac Allante.
All Fiat 124 Spiders have a pininfarina 'F' crest on the lower rear fender. The pininfarina badged cars had pininfarina written in letter form.
Just keep in mind that your favorite Ferrari was most likely also a product of Pininfarina design.
