This is the Zender Vision 3. Hans-Albert Zender had six four-wheeled visions in the eighties. This appeared on the scene around the same time the Ferrari F40 did. It also remained a prototype.
Zender loved to experiment with fiber reinforced plastics. He started by making bucket seats, continued with his own wheel arch extensions and soon ended up in the aftermarket and tuning industry that was booming at the time in Germany. Still, like many others, he wanted to build his own car using composites.
