The Maserati Spyder was presented at the Turin Motor Show in November 1984, three years after the Biturbo on which it was based. The wheelbase was reduced by almost 12 cm (4.5″) to 2.4 metres (94.5″) with styling by Zagato of Milan, where it was also assembled. The engine had a displacement of 2.0 litres for the domestic market and 2.5 litres for export. Folding roof with Alcantara headlining. Launched with leather interior and a Maserati gold watch on the dashboard. Among the 3,793 buyers of all Spyder versions were four F1 champions Alain Prost and Sir Elton John, as well as Mrs Ursula Piech, whose husband was head of Audi at the time.
