I went to Cuba, and they were a good amount of Kia Picanto, Daewoo and cars from China brands I could not recognize. Of course they can't import from the US due to the embargo, and Europe would be unreliable for after-sell service.
They trade, limited by their own poverty, with countries that can't be easily bullied by the US.
Peugeot is the biggest foreign car brand in Cuba.
But it has to be said: the entire car market in Cuba is few thousands cars per year.
