Greg Mills and Emanuele Pirro

Dr Mills heads the Johannesburg-based Brenthurst Foundation, is a board member of cycling’s Team Africa Rising, and has authored eight books on motorsport, including most recently Saloons, Bars & Boykies; Pirro is a former F1 driver for Benetton and Scuderia Italia, a F1 test driver for McLaren, and a five-time winner of the Le Mans 24-hour race for Audi. Both were, a long time ago, go-karting rivals and champions with big dreams.
