If memory serves me well, Yugos were made in former Yugoslavia and were known for being extremely cheap and dangerous for everyone in and around them. Am I correct?

But this makes me scratch my head.

American manufacturers exist in Europe today and regardless of not being a fan the cars sell, regardless the constant attempts to introduce pure US models, like the F series.

Ford may be the most widespread manufacturer but I've seen a few Dodge, Chevrolet (but GM officially pulled from the market after a 3 years run, stating it wasn't willing to remain in a market where a minimum 25% of market share wasn't attainable; competition sucks, apparently!), JEEP and Chrysler.

What is stopping these brands to import back the technology being used here, on their european models, back to the home country? It's already owned here!

I remember reading an article on a joint project between GM and FIAT to develop a new and shared platform. After X number of years and a gross amount of money invested, GM drops the project, FIAT finishes it and starts building an entire new generation of cars, still being built today.

Why put time, money and effort into a project to just drop it? Having a shared platform, capable of being used to assemble vehicles on both sides of the ocean makes sense.
