a car
walter : i think you are right, that must be a "goliath". the only other three-wheeler i remember was the "tempo". the company my dad worked for had a tempo and i was on occasion allowed to sit next to driver when some goods were to be delivered in the port ... and i was even allowed to turn on the directional sign (those litttle red fingers sticking out from the car - oh, what fun ).
in 1950 i was rich enough to buy my own motorcycle, a "imme" (it sounded like a wild hornet when driving at top speed of about 65 km/h ... and no safety helmet !!!). sadly, i had to leave it behind when heading to canada.
btw it might be suitable transportation for anyone wanting to beat the traffic congestion in london. i recall that the advertising featured someone driving the "imme" down a railway track ! it's unique suspension allowed it to overcome many obstacles. i at one time didn't slow down when coming home and went right over the curb and up on the sidewalk, without much harm to driver or motorcycle. hbg
