Of course, Cuba is associated with running old American cars – well, they have no choice as after the revolution all imports from the US ceased and the Cuban people had to make their cars last. And they do make them last. In fact, few have original parts and their big gas-guzzling motors have long been replaced by more economical diesel engines. They are often used as taxis because a) the tourists like them and b) it’s possible to cram more people in and make more money on each trip.
