Fans of VauxhallOpel sporting models don't get many chances to celebrate, but the new Opel GT Concept unveiled at Geneva ought to raise a cheer.br br The sporty new coupe is the design team's homage to the Vauxhall XVR and Opel GT from the sixties. Vauxhall has billed the GT Concept as a “forward thinking” design study that builds on the striking Monza show car from 2013. The suggestion is that the GT Concept could point the way to a sexy and sporty new Tigra model, but as yet the company won't confirm anything.
