"Third world" sales is unlikely to happen in significant numbers:
- US motor vehicle standards may or may not be accepted in the rest of the world. (Red turn signals, etc.) Replace taillamps $$$.
- Instrument labelling on originally-US-market vehicles ("Miles?") is gibberish in almost the entire rest of the world. Replace instrument cluster $$$. At least the 100,000ish Canadian-market vehicles won't have this issue.
- ULSD fuel necessary for operating these vehicles may not be consistently available outside the developed world. I'm not sure how much of the rest of the world has switched over.
- Would the remaining potential destinations be able to pay enough for the cars, and shipping them, to make it economically viable?
- Why should someone in the destination market buy one of these instead of a locally-available model? Why should a VW dealer there sell a fixed imported-from-USA model instead of a locally-available new model? Parts availability - Warranty?
- Does VW want these cars showing up in places of conflict, potentially being used by "the wrong side"?
It's possible that *some* of the cars could go this route, particularly the Canadian models that already have metric instrumentation, but at a certain point it just isn't worth the trouble.
If VW gets an approved fix for these cars, it makes more sense to fix and sell the best 30% over the next two years in their original market (and in the absence of any new TDI models, that number is about right for the size of that market), keep another 10% - 20% for spare parts (junkyards that part out the cars will buy a certain percentage of them - the market will dictate how many), maaaaaaybe export a few of the Canadian buybacks after they're fixed, the rest will get flattened.
