This is latest version of Porsche's open-top coupe. At the touch of a button, a large, transparent glass roof slides back to give occupants a clear view of the heavens. Distinguished from a normal 911 coupe by its distinct, sharp-edged rear side windows, the Targa will be exclusively four-wheel drive. The Targa is the perfect compromise for those who just can't decide between a 911 coupe and a convertible. Expect it in early 2007.
