BMW Individual created by German designer Sonja Kiefer
For the external colour Sonja Kiefer decided on Sepia Metallic lacquer, which flares between gold and lilac/mauve. Since the sky over the seats can be open, the designer selected Arizona sun yellow leather with piping in the same colour. The remaining interior equipment is from black leather.
