1958 Zunndapp Janus
Germany’s Zunndapp company specialized in motorcycles before jumping into the car business with its 1958 Janus. The results were less than impressive. The Janus traveled at top speeds of only 50 miles per hour, using only 14 horsepower. The rear-facing back seat was an interesting quirk, but it couldn’t save the slow-and-ugly Janus from automotive infamy.
