During races, it was fast and easily maneuvered so no other car stand a chance. But people loved it purchasing every one of these quick little cars they could find.
In 1956, Porsche started to produce the 550A, a slightly modified Spyder. It was a hit, shocking the entire world by winning in its first Appearance in Targa Florio, a brutal road race. It also humbled well-known and more powerful rivals such as Ferrari, Maseratti and Jaguar. In the next five years it won almost all the races in which it competed. It became a car that attracted more attention for its occasional losses than for the nearly non-stop victories.
