The 1972 Alfa Romeo Alfetta Spider by Pininfarina was a proposal for a targa-top convertible based on the transaxle Alfetta platform. When the Alfetta models were introduced in 1975, only a Sprint and Berlina appeared, and enthusiasts wondered where the new Spider was. In 1972 Pininfarina had proposed a replacement for the Duetto and intended it to appear with the Alfetta Berlina and Sprint, but there were simply no funds for its development. It was presented at the 1972 Turin Motor Show. The prototype is now housed in the Museo Storico Alfa-Romeo in Arese.
