Pablo Escobar's 1974 Porsche 911 RSR listed for sale

A Porsche 911 RSR – once owned by Colombian drug lord Pablo Escobar – has come onto the market, with a US$2.2 million (AU$2.9 million) price tag. The bespoke rear-engine German sports car was designed and built for the 1974 International Race of Champions (IROC) all-star competition, where it was assigned to Formula One driver Emerson Fittipaldi. After that year's 15-car series wrapped up, the vehicle was acquired by automotive and motorsport business magnate Roger Penske.
