Sounds like the American Pickers was the Ian Hellings one. If so there was an Iso floating about too. His take on the whole thing was quite amuzing.
Yep, IC were painted as often as they were washed. Much of the damage for and aft was caused by stone age comedians thinking they were the first to have the idea of moving these small cars somewhere daft, ignoring that the 'owner' was invalid. I myself have helped a guy in Bristol retrieve his Type 70 from the middle of a roundabout. The same thing used to happen to microcars, including Faringdon, until I smacked one of the said comedians in the face. He did not find that very funny and his mates all ran away. Of course now I would go to prison for standing up for myself. But at the time the town received the message and understood. Leave the cars alone or suffer the consequences.
It must be said that some of the folk who had the IC were not that good at driving, and of course it was not their car. If they had a fail, they just got given another one. So reference baiting IC drivers. Not a good idea, as once issued with a type 70, they had the means of retribution, could catch up miscreants and drive into them full in the knowledge they had a nice new IC waiting at the agents. Disabled one, able bodied 0. I have heard that tale from several disabled folk.
Like I say these iIC are more than interesting cars, they are social history, if you bother to listen to folk talk.
