Despite the Porsche 911’s immense and ongoing success, the 356 series has always maintained a loyal fan base. The 356 was, however, a notorious ruster, which claimed many of the 76,000 built from 1948-1965. The rarest, including the first 50 or so coupes hand-built in Gmund, Austria between 1948 and 1950, plus some later models, can fetch $1.5 million.
