A particularly important aspect of this example is its fully matching numbers status (engine and transmission), combined with the rare distinction of retaining its entirely original paint – a combination seldom encountered on Flatnose cars today.
The Flatnose design itself draws direct inspiration from the dominant Porsche 935 race cars of the late 1970s. In response to strong demand from select clients, Porsche introduced the option 505, bringing this radical motorsport aesthetic to the road in extremely limited numbers.
At the time, this transformation was far from a simple option: the Flatnose conversion was carried out under the Porsche Sonderwunsch, involving extensive hand-finished modifications. Reflecting this exclusivity, option 505 was priced at exactly $23,244, positioning the car among the most expensive and bespoke Porsche offerings available to private clients in the early 1980s.
This particular car is furthermore specified with a comprehensive list of desirable factory options, including:
139 – Heated driver’s seat
158 – Blaupunkt radio
197 – Stronger battery
220 – Limited-slip differential
340 – Heated passenger seat
437 – Comfort seats
490 – Hi-Fi sound system
533 – Alarm system
650 – Electric sunroof
07154 – Wheel caps painted in body colour with Porsche crest
A particularly noteworthy element accompanying the car is the presence of rare factory-issued documentation specific to the Flatnose (option 505), including:
– The original factory repair manual dedicated to the Flatnose configuration
– The corresponding technical specification sheet for the Flatnose
Material of this nature is seldom retained with the car and provides valuable insight into the engineering and specificities of the Sonderwunsch-built Flatnose models.
Altogether, this Porsche 930 Flatnose represents a rare opportunity to acquire a highly original, matching numbers example in a particularly refined and uncommon specification – a true collector’s piece from one of the most extravagant chapters in Porsche’s history.
