Motors, so the project was dropped. One non-functioning 1:1 scale model from the beginning of 1997 remain, that has been kept hidden for more than twenty years, and revealed for public on the thirtieth anniversary of the Calibra A world premiere. Now the red painted model is exhibited in the underground garage of Opel Classic. As a non-functioning study, it had only a very schematic interior and two different type of headlights (left and right) to test various design solutions at the front. 2007 GTC Concept The Opel GTC Concept of March 2007 was linked to the Calibra name, but no production version resulted from the concept car. The GTC concept car was rather a design projection for the first generation of Opel Insignia introduced next year, and especially its most powerful OPC version, which inherited the concept car's large emphasized vertical intakes at the front, similar exhaust tips at the rear and rims on the side. The interior of the first generation Insignia is also very similar to the 2007 GTC Concept. The GTC Concept is showcased in the concept car section of Opel Classic.
