Zender, based in the German town of Mulheim-Kerlich, provided Alfa Romeo with factory bumpers, spoilers and skirts during the late 1980's and early 1990's. Their range also includes accessories such as alloy wheels, pedals and gearknobs.

Building a working protoype was a somewhat unusual step for the company. However it is a standard Alfa 75 floorpan and mechanicals, unmodified, mated to an all fibreglass bodyshell. The Progetto Cinque ( Project Five ) is a pure roadster with no provision for side windows or a hood.

Zender tried to create a modern interpretation of the "Spider" theme, using a mixture of classic styling cues blended into an up to date shape.
