When I ordered my CX-5 I was informed by the dealer that Mazda, like most other vehicle manufacturers, have some models series produced elsewhere other than Hiroshima with Mexico being popular. The production line in Hiroshima which does produce the CX-5 is also shared with the CX-3 and whilst I cannot remember exactly the time period I think it was along the lines of 1 month CX-3, the next month CX-5. That's the main reason why I was advised that I got my order in just in time as it was the last accepted order for that production run. The dealer also informed me that that when producing, a new CX-5 runs off the line every 13 minutes. Wow.
This does have some advantages in that because I knew the date of the production run I was able to search online and find out which car transporters left the port of Hiroshima within the right timescale. This led me to the ship 'Adriatic Highway' and I subsequently tracked her passage from Japan up until she finally docked in the north German port of Emden. In the case of the CX-5 I don't believe that they are produced in enough numbers to be found lying around quaysides for very long.
