- "You built a time machine... out of a Yugo?"
- —Marty McFly talking to Marcus Irving
The partially working Yugo time machine.
The Yugo GX, also known simply as the Yugo, was the American version of the Koral, a car manufactured by the Yugoslav Serbian Zastava corporation. It was sold in the United States by YugoCars, a company based in Sun Valley, California.
In 1986, Marcus Irving used a Yugo to create a partially working time machine.
