- Colour
- Grand Prix White with red bumpers
One of only 55 examples built, this Grand Prix White Porsche 911 Carrera RS 3.0 was a homologation special created to qualify the RSR racer for the 1974 season, featuring detuned RSR mechanicals, 917-derived brakes, and a bare-minimum 900 kg kerb weight. Sold new in Stuttgart on 10 January 1974, it passed to Italian club racer Antonino Guagliardo, who entered it in the 1975 Targa Florio with Cefalù Corse. Guagliardo retained the car for roughly three decades before it passed through France and into a Belgian dealer's hands, ultimately joining the Stuttgart Legends Collection in 2015.
