Rare vintage speedsters include the original Porsche 356 and the Porsche 356C. One of the rarest and most desirable vintage Porsche speedsters in this category is the 1952 roadster 356 America; only four models were ever sold in the United States. Experts estimate that less than half of the original 76,313 Porsche 356 series vehicles survived as of 2015.
The first line of Porsche 356 speedsters, made between 1948 and 1955, are the rarest production line in the group. The company only produced 7,627 cars during that period. The first 40 models in this line feature aluminum chassis hammered into shape over wooden pattern forms.
The subsequent Porsche 356A, produced from 1956 to 1959, features a larger engine and a single-piece windshield. An especially rare 1957 Type 2 model features window frame wind wings and extra large rear windows. Experts consider the Porsche 356B to be the precursor to the more modern 911 sports car, due to its distinctive shape. This speedster offered buyers a choice between a 60-horsepower engine, a 75-horsepower engine, or a 90-horsepower engine.
The Porsche 356C is the first model of its kind to feature disc brakes. Porsche produced this model for a short time, from 1964 to 1965, before it became obsolete with the release of the Porsche 911 and 912.
