Plain and simple American cars are unique to the USA and don't necessarily fit the foreign car marketplace. Not to mention many foreign countries make it difficult for us makers to competitively sell there, while at the same time we have an open door policy. Look at china for example they won't even let you sell there without a "Chinese partner" company. So if us cars in a foreign country are double the price there will be less sold. Hard for Foreigners to fall in love with a product when it out of reach, therefore they have little positive experience to share about us cars.
