There's been a spate of vehicles given the roofless treatment since 2003, which helped keep registrations of convertibles growing since then. 2007 saw the trend reverse, though, with registrations of droptops sliding by 8.6 percent, says R.L. Polk & Company. Polk's folks contend that while there's now plenty of selection with fancy retractable hardtops, the economic slide is putting downward pressure on some luxury items. While it might be difficult to describe the ghastly petrochemical disaster inside a Sebring as profligate, convertibles are not viewed by consumers as a sensible shoes purchase. Segment leaders such as the Mustang and Sebring still maintain their dominance, with the Mustang taking a 33 percent hit compared to 2006, while the Sebring actually found 2.7 percent more registrants. If you hate convertibles, this news doesn't matter to you. The upside is that as inventory ages on lots, deals get hotter.
