In 1956, Mannesmann, a German industrial conglomerate, acquired the licences and began building Porsche tractors in serious numbers. By 1963, when production ceased, it had built more than 125,000 of them.
Unsurprisingly, certain Porsche and Lamborghini tractors command high prices today. For example, earlier this year, a fully restored 1958 Porsche-Diesel 308 Super N made £19,833 at auction and a restored 1960 Junior 108 L, £13,200. Prices for collectable Lamborghinis vary widely. In 2016, a restored 1955 Lamborghini DL25 like Ciro’s (his was built in 1954) sold for £86,000 at auction in the US but another, equally pristine, example made just £9440 in the UK.
