My thanks to Martin Stein for sending me these pictures of a 3-wheeled Fiat 500. Martin writes: Here are some pictures that make me smile. ( I am a club-friend of Ingo Kaup with the unknown 3-wheeler.)
I saw the Fiat 500 "car" in Dortmund on a Fiat-Meeting. It is powered by a Zyndapp 50cc Special. If you turn right the car goes left and viceaversa. Martins' Email address is: Martin@iglippe.de |
