Entirely handcrafted by Canadian engineer Herb Jordan, these miniature Porsche engines – one a scale replica of the Carrera ‘Four-Cam’, the other of the turbocharged 917/30’s flat-12 – are fully operational, though admittedly haven’t been run for many years. They will be offered by RM Sotheby’s at its ‘Driven by Disruption’ sale on 10 December, both estimated at 20,000-30,000 dollars. With some careful fettling, you could be enjoying the distinct Porsche engine notes (albeit at a much higher pitch) without having to brave the cold this Christmas.
