About this car

This is chassis 0124, one of the 15 Porsche 911 RSRs built in 1973 for Roger Penske's International Race of Champions series, in which identically prepared cars were drawn by lot among top drivers from F1, IndyCar and NASCAR. It is described as the most successful of them: it won both races it entered, with George Follmer and then Mark Donohue driving.

After the series it passed to Al Holbert, who raced it in the 1974 IMSA Camel GT and Trans Am championships. A testing accident at Mid-Ohio ended its racing career. Later owners included author John Starkey and Ulrich Schumacher, who had Karosserie Stimming restore it to IROC livery and specification in 2009. It carries its correct 911/72 engine, rebuilt along with the gearbox, and is finished in its original Black 041.

The cabin keeps period detail, with Recaro seats, four-point harnesses and a fire extinguisher. The paintwork is reported as having only a couple of light chips on the rear arches. The history file holds the German Fahrzeugbrief, road registration papers and restoration records, and the car features in Matt Stone's book on the IROC Porsches.

Porsche 911 buying guide

The Porsche 911 has been in production since 1964 and has kept the same basic layout throughout: a flat-six engine mounted behind the rear axle, two seats up front and two small ones behind. The range runs from the everyday Carrera and Targa to the four-wheel-drive Turbo and the track-focused GT3 and GT3 RS. Buyers choose it because it works as a daily car, is well built and has a large network of independent specialists.
