Nonsense.
Darren,
This is not necessary for the UK Govt car import form. The requesters are stupid there.
These numbers just don't exist officially. Just tell them.
We know nowadays how many 230ies or 280ies were built, how many were exported and perhaps how many were sold to Germany. But the Daimler-Benz internal statistics do not tell us how many had manual or automatic gear change - at least not divided by the countries.
In total 19831 230ies were built among which roughly 6200 were automatics and the others about 14000 Schaltgetriebe-cars (stick-shift).
And ah yes, there were more engines built than cars.
Good luck
Achim
