Automotive News reports convertible registrations, which grew steadily the past several years in the United States, slumped in 2007, dropping 8.6 percent. It's the first year since 2003 there's been a drop in registrations of vehicles designed to let the sun shine on in — even including a 1.2% drop for both No. 1 New York and the 2006 leader, Los Angeles compared with the year before. Apparently the economy hurts everything — convertible sales included. Will the market for 'verts drop even more in 2008? Guess we'll find out about a year from now. [via Automotive News (sub. req.)]
