FW 11
In 1977 Marcello Gandini designed the FW 11 for Anadol and Reliant, the latter naming it as the Scimitar SE 7. Four prototypes of this car were produced, two of which were sent to England with the Reliant badge, and two other examples, one of them white and the other one blue, were sent to Turkey with the Anadol badge. The car, which had a modern design and "luxuries" for that period's European cars such as electrical windows, was deemed too expensive to produce profitably by Anadol and the project was shelved. The two Anadol prototypes were held in Koç Holding's (which owns Otosan) depot in Istanbul's Acıbadem district for nearly 25 years. Today, one of them is displayed at the Rahmi M. Koç Museum in Istanbul, since 2004.
One of the other prototypes, the Reliant Scimitar SE 7, is currently displayed in England. Following Anadol's decision not to build the FW 11, Reliant exhibited the Scimitar SE 7 at its stand as a prototype during the Birmingham Motor Show.
The FW 11 design was later purchased by Citroën, and with little changes (e.g. a steel unibody with steel and plastic panels instead of fiberglass) it was mass produced as the Citroën BX for 12 years, becoming a "best-seller" for the French company.
