Ferrari never developed the Testarossa into a spider version for production. There were a handful of wealthy collectors who, wanting to own a convertible version of this sublime model, commissioned a derivative from coachbuilders such as Richard Straman in the United States.

The Ferrari Testarossa on offer is exceptionally unique. It was built specially at Maranello for l’Avvocato Gianni Agnelli, to mark the anniversary of his taking over the multinational company Fiat.


According to Ferrari archives, the construction of the body started on February 27, 1986, and was finished and delivered on June 16, 1986. It was registered in Turin with the personalized number plate TO 00000G. The service book, in the name of I.F.I Spa (the financial company owned by Gianni Agnelli) recorded the warranty as starting on June 13, 1986.

Looking closely at this very special Testarossa, it is clear that it has been very carefully designed. It was not simply a case of crudely removing the roof and replacing it with a hood and rear cover.Finished in “Argento” silver with a “Blu” interior, the Valeo has a special electronic clutch system designed specifically for Agnelli, who due to a prior injury with his left leg presumably had difficulty operating the clutch pedal.


This true one-of-one Testarossa was sold at auction at Rétromobile 2016 by Artcurial Motorcars for approximately US$ 1,333,145.
