When you are a man like Gianni Agnelli in 1986 - one of the richest men in recent Italian history - what would you drive? A bespoke Ferrari Testarossa Spider, of course. Heir to the Fiat empire, money wasn't an issue for Agnelli and neither was knowledge of the automotive industry, two reasons enough to justify a special vehicle like this. Tailored to his exacting specifications, this one-off Testarossa Spider is a wonder from every angle, delivering 390HP via its 12-cylinder engine, five speed trans, and front and rear independent suspension. Totalling only 22,000km on the clock, boasting a silver cast Cavallino Rampante on the hood, and coated in a gleaming silver paint inspired by the "Ag" (silver on the periodic table) that starts his last name, you'll have to bid high and often until the auction closes in February to have a chance.
