Opel GT concept
This concept car riffs on Opel's original GT concept car of 1965, but it was designed with minimalism in mind. Designers were so eager to cut down on cluttered exterior lines that they got rid of regular side windows altogether, instead using "transition glass" so the door and window blends together seamlessly.
Unlike the 60s concept car, there is no guarantee this vehicle will go into regular production.
