Background on Japan’s 1960s Police Vehicle Fleet
In the 1960s, Japan’s police departments customized a small fleet of Porsche 912s for patrol duties, primarily in Kanagawa Prefecture. Only four such vehicles are believed to have been modified for law enforcement use, making them exceedingly rare today. The Porsche 912 was chosen for its performance and reliability, suitable for high-speed patrols on busy expressways.
The vehicle in question served from 1968 until 1973, after which it was retired due to engine failure. Its preservation was unusual, as most police vehicles were scrapped after service. The vehicle’s history was largely forgotten until recent efforts to recover and restore it gained attention.
“This Porsche 912 police car is a unique piece of automotive and law enforcement history, especially given its rarity and the fact that it was preserved for so long.”
