Just for fun, what is the first motor you remember - either riding in, or just being aware of ?
For me it would be my Dad's navy blue FIAT 500 (the old, sensible sized one). This one had a fold back roof so in those pre-seat belt, safety nanny days I could stand on the passenger seat and poke my headout of the roof "tank commander" style whilst driving through Lancaster.
(this isn't it, just an identical one - his died due to over use).
