History
The first Iso Rivolta revival began in autumn 1989. The Grifo 90 was shown on 12 June 1991 at Villa Freni in Modena and was planned for 200 cars a year from 1994 at Conversano, but the project stopped abruptly in summer 1992 when the bus business behind it failed. In April 2010 the car was shown at Villa d'Este and the page says it would now be built in only 12 examples, all with Corvette V8 engines, at the Mako Shark plant in Dolzago.
