Just like in the picture 2, with blackened windows, with no interior, the first Lamborghini is presented at the Turin Motor Show in November 1963. As far as known, is likely this the prototype probably the first car to have been shown at a trade show, in which is placed building material as a substitute for the missing engine on the front axle, so that the springs of the front axle are somewhat pre-stressed.
The reason is not an incomplete engine, but a strange dissonance between this and the planned opening for it. In short, the engine will not fit at all in the to late completed body. It will be previously presented to the interested journalists on the test bench. And so no one asks the reason for the non-opening hood of the prototype.
