On 21st May, the Canadian 1991 Grand Prix-winning Benetton B-191-02, driven by Nelson Piquet and Michael Schumacher, will go under the hammer at Bonhams The Spa Classic Sale. In 2016, it underwent a complete rebuild, with the engine, gearbox and chassis all radically overhauled. It’s in excellent running order, and with an estimate of around £750,000, so it very well should be.
