I've read the problem on this forum, but I haven't found any solutions or tips.

I have built a great empire which is able to generate 1-2 million bucks a month even from only 4 markets (Austria-Hungary, Germany, Belgium and Switzerland) during the troubled times of World War. Around the end of the war, small cars just stop selling without any particular reason, everyone wants to buy middle-ranged ones and limusines. No problem, I can wait a few years producing and selling only middle- and upper-class cars... But even around 1920-22, when I can oparate my business again throughout Europe, no one is willing to buy any small cars from me, even if I design a brand new model and sell it for $ 85! What could be the reason?
