After the 1973-74 IROC series, all sixteen cars were individually sold by Penske to privateer drivers and collectors and continue today to occupy a unique part of Porsche racing history.

We are delighted to offer for sale this famous race-winning example, which has been authentically preserved and remains fitted with genuine type 911/74 IROC RSR engine, which was fully overhauled by Porsche Centre Melbourne in 2014 and used sparingly since.

This immensely historic Porsche is offered for sale with all UK duties paid / or can be made available for immediate export.
