As far as I know, no South American country ever bought the Harrier.
Certainly, if you had seen the large audience of expectant voyeurs at Sao Paulo (the biggest city in Brazil) watch the RAF rebuild most of their ground equipment, assemble a Harrier and then take it to bits again without the engine ever having been started would possibly have attracted a bit of a politically negative audience. (the population of Sao Paulo is around 11 million people).
Things might have been quite different if the Harrier had duly got airborne and done a decent display.
