Appreciate your response but it hasnt specifically answered my question.
Users of this primarily UK/European based Forum have models made for the UK/European markets typically of the Daewoo and South Korean plants.
The USA markets had/have vehicles made to cater for the USA customer base (generally the larger gas guzzlers) and have different components.
Getting parts for UK/European clients may be a completely different situation. Having 'partners shops' all over the USA for USA models is one thing, having a part for a small European vehicle may be a bit more if'y.
Surprisingly the Spark I understand was a reasonably good seller in the USA so possibly you can 'cut your teeth' on proving what you can do by finding the blower motor for Louise Smith who posted very recently.
Apologies if I sound sceptical but when members of this Forum can virtually exhaust virtually all possibilities throughout the whole of Europe of finding the parts they require, the chances of a part being in America for a model which possibly wasnt even sold there sounds a wee bit optimistic.
