You found it again!

The Jacaré was designed by Eddadesign, a studio from Barcelona, for Swiss company Giba Holdings, and presented at the 2005 EICMA (Milan motorcycle show). It was to be powered by a trial motorcycle engine supplied by Gas Gas, a small manufacturer from Gerona, North of Barcelona. When the recession hit the project was shelved for a few years, but then resurrected sometime around 2012. The plan was to build the cars at the old Derbi motorcycle factory in Martorelles, owned by Piaggio and now closed. At that point it was also announced that Piaggio would supply the engines instead. Negotiations for the factory fell through and later Giba announced that they had acquired a plant in Santa Oliva, Tarragona (very close to where I work). Giba requested grants from the Catalan government citing the employment they would create but the authorities refused, judging their business plan underdeveloped and non-viable, so Giba relocated once again, to the town of Almansa, Albacete, in the South of Spain. They were able to obtain some support there from the local government, and started a widely-publicized recruitment process (just before the local elections), but eventually it became clear that the car was not actually moving forward to production. The whole thing finally collapsed and Giba executives were deemed scammers who never had a solid entrepreneurial plan and were just trying to get government subsidies.
