The history of racing is full of one-shot-wonders and flashes-in-the-pan. It is an unforgiving sport where everything unfolds in public and a victory today does not guarantee anything tomorrow—except another chance to lose. In the course of only three short years, the Cobras had proven themselves to be tenacious. They cut their teeth in SCCA racing in this country and after the initial problems were resolved, Cobra roadsters experienced the type of reliability rarely seen in sports car racing. They transformed Chevrolet’s dramatic, new Corvette Sting Ray into a perpetual backmarker. Then the factory team expanded its horizons, competing in the U.S. Manufacturer’s Championship. They became the cars to beat in that series, too.
