1958 Zundapp Janus
Zundapp Janus was a failed attempt by a decent motorcycle company at crossing over into cars, and for that reason remains the company’s only foray into that market. You can understand why it was named after the Roman god with two faces, one facing forward and the other facing back, because the car looked the same on both ends. You had a 50-50 chance of guessing which direction a parked Janus was pointing from the outside. It had a rear door and front door as well but these features didn’t help it sell.
