Here's a guy that is truly off his rocker.
"There are few if any models in the world to rival the Ferrari 312PB built by Pierre Scerri of Avignon, France. This 1:3 scale marvel is the real thing in every sense, from its operating 12-cylinder engine to the exact scale operating Ferrari gauges which are calibrated precisely to indicate rpm, oil pressure, water temperature and oil temperature.
It took Pierre 15 years and more than 20,000 hours to build this car. He learned to make glass so he could make the exact pattern lens for the operating headlights. He learned to make rubber so he could mold his own tires. His computer mainframe design background with the French telecommunications system allowed him to duplicate the Ferrari electronics system in exact miniature. It also provided him with the understanding needed to make a 1/3 scale operating fuel injection system identical to that in the full-size Ferrari.
Perhaps the toughest aspect of the car was the gearbox, for which Ferrari supplied drawings. While Pierre had an understanding of the object to be built, he lacked the very expensive specialized equipment required to build high-tolerance gears and synchros. Colleti, the builder of the full-size cars gearbox ended up building the models gearbox."
