This 1964 Porsche 904 GTS, chassis number 904 012, boasts a rich history, having been owned by actor Robert Redford and raced in prominent North American venues under the Otto Zipper Precision Motor Cars banner. The car retains its original bodywork, chassis, transaxle, and suspension, documented with a factory Kardex and extensive history file.

While restored in the early 1990s with an early 2-liter 911 engine, a common and period-correct upgrade, the original four-cam engine is available separately. This Porsche is a rare and desirable example, offering entry into historic racing events and concours d'elegance.
