a military guy bought this '66 Honda S600 new in Japan, brought it home to the states and drove it for a decade before selling it to a Honda dealership, who has displayed it for 4 decades... and now it's up for sale on BaT

and it has dual outboard chain-drive assemblies powering the wheels... that has to be the most recent and probably the last chain drive car from a mass manufacturing factory
