Take a look at the latest BMW model called “Zagato Roadster” released after three months after the coupé version of the car, which debuted earlier this year at the Concorso d’Eleganza Villa d’Este in Italy. The one-off concept is a collaboration between the German automaker and Italian coachbuilder Zagato. The two Zagato concepts are variants of the BMW Z4 hardtop convertible. Both feature a “double-bubble” roof. Details include a grille with Z-design grating, two circular headlights and a three-dimensional front apron. A set of 19-inch light-alloy wheels rounds out the package. The cabin gets brown leather touches and brown “Z” embroidery into the seats. Enjoy!
