Lexus will have three worldwide model debuts at January's North American International Auto Show in Detroit. The production model of the all-new 2002 SC 430 hardtop convertible, which goes on sale in March, will be shown. The luxury manufacturer also will debut two variations of its IS 300 compact sport sedan, including a five-speed manual transmission model and an all-new SportCross model. The 2002 IS 300 SportCross has the same performance as the sedan, and features a new design with a fifth door for increased versatility and utility.
