One of the most highly-sought 911s ever, the 911 Carrera RS is an icon among icons. Designed built to meet motor sport homologation requirements, the “Rennsport” models were lighter, more powerful, and more focused than other 911s at the time, and the car’s styling reflected its thrill-seeking nature. Generally fitted with a spartan cabin, stiff suspension, and big brake kit, the 1973-1974 Carrera RS was a driver’s car through and through, which is partly why they’re almost impossible to find.
