Convertibles must've been hard to keep on dealer lots back in 2006, when the reclining-roof rollers accounted for 2 percent of all new vehicle sales. That amounts to nearly 350,000 drivers letting the sun shine in. In 2010, however, total convertible sales fell over 50 percent while market share dropped to just 1.2 percent.
If one automaker wanted to declare victory in this declining segment, it would be General Motors. Through the first part of the year, the 2011 Chevrolet Camaro Convertible has accounted for 12.4 percent of the droptop market. The Ford Mustang isn't far behind, making up for an even 11 percent.
