Go and ask Porsche..the only way to check the VINs.
You are right with the limited numbers in the US, the ROW cars had different colors and there is no known limitation..check the mcodes M97, M98 and M99.
The 87/88 CE are all made in the beginning of the MY, but the 875 VINs are all over the place and not a complete series.
I heard from over 1500 "89 SAs" all over the world, that is why I expect the same (for CEs and SEs).
The other ones are not as nice as the US SAs.
