The VW Caddy was basically a Seat Ibiza compact car (not sold in the US of A) with a van shell smushed onto its back. It was cheap to design, cheap to build, and great for small businesses. Flying, as it turns out, wasn't its forte.
But it wasn't the jump that killed the van, it was the landing. You can actually hear the cameraman scream "ACH SCHEISSE!" when the little VW crashes into the ground, totally killing the rad-ass application of the horn. "Der steht" pretty much means "He's done." We concur.
