Records indicate that three MGA were assembled in Cuba, just before the Castro revolution and the shipping embargo. And one was a Twin Cam! A few others may have been shipped there indirectly from the USA. The CKD cars would have been shipped prior to the 1959 shipping embargo, so those would be 1500 models. Due to shortage of raw materials and parts in Cuba, the CKD cars were shipped with all parts required for assembly.

There are a few MGA resident in Cuba to this day. I have some information on at least three MGA currently there (maybe four), and considerable detail on the current condition of one in particular. Which one may have been the CKD car is still unknown. See here: http://mgaguru.com/guest/demis/da2.htm

Two photos above right come from the vintage car club of Cuba, Club de Autos Clasicos y Antiquos.

There is also a YouTube video "Jeremy Clarkson's Motorworld ¦ Cuba S02E02" with Jeremy driving an MGA (with a Lada engine), photo at right.
