Here’s something to think about: every seven-and-a-half seconds, someone, somewhere in the world, is purchasing a General Motors product. And most of those are Chevrolets of one kind or another. The newest model to hit the asphalt in North America is the Camaro convertible. According to Russ Clark, Camaro product marketing director, the coupe version caught and passed the Ford Mustang in overall sales last year – the first time since 1985. “It’s now the segment leader,” he said at the convertible launch in San Diego, “and 90 per cent of the cars have been sold through retail sales, with no incentives.”
