BMW and Zagato seem to have deemed that their initial collaboration on the BMW Zagato Coupe wasn’t enough. The follow-up Zagato Roadster was conceived, designed and produced in just six short weeks in order to be ready for its debut this weekend at the 2012 Pebble Beach Concours d’Elegance. For the most part the vehicle is a droptop version of the Coupe, with nearly everything else the same as the original Z4 Roadster makeover, however, the entire rear end was redesigned, giving it a more balanced look. Details such as leather-wrapped roll bars seal the deal. Strictly a one-off.
