Among Bob Lutz's less brilliant ideas, the Solstice and Sky were supposed to rejuvenate GM the way his Viper did for Chrysler. Rushed into production in mid-2005, the Solstice created an initial sales fever that quickly cooled off when news got out about the quirky top and the absolute lack of any storage space. Sales peaked at 19,710 in 2006 but then tumbled all the way to 4,826 by 2009. The Sky did even worse. It reached sales of 16,567 in 2007 and two years later sold only 4,178.
