In February 1954, 550-07 went into production as a prototype 550. It was given to Wendler Karosserie in Reutlingen in a special arrangement to demonstrate their coach building skills to Porsche to try and secure the contract for the remaining prototypes and the type 550 customer production builds.

550-07 was built as a race-test car for Porsche and was the first Wendler built car on a Wendler built frame.

It was first sold to the Paris Porsche dealer Sonauto, owned by Auguste Veuillet who promoted the upcoming Montlhéry Coupe du Printemps race in it. The 550 was entered into a number of races including the Tour de France with Annie Bousquet and Marie Claire Beaulieu as drivers. In February 1955 Bousquet raced the spyder again in Morocco for the Agadir International Circuit race.
