The Zender Vision 3c was a concept car built by the German tuning and design company Zender as a convertible study derived from its Vision 3 coupe. It followed an earlier preview shown at the 1986 Geneva Motor Show, where Zender displayed a 1:5 scale model of a cabriolet version of the Vision 2 under the name Vision 2C, which was never intended to be built in full size. The Vision 3c, presented a year later as a full-scale 1:1 model, used a lowercase "c" in its name to denote its cabriolet form.
Its design closely followed that of the Vision 3 coupe, sharing the same angular yet flowing lines. The mid-mounted engine was concealed beneath a sloping hump positioned behind the seats. The rear end carried a distinctive treatment, featuring a crease running the full width of the body with three rear light cutouts arranged beneath it on each side.
