Trabant P70 Coupé
I hate to spoil the party, but officially there's no such thing as a Trabant P70 Coupe to the best of my knowledge, as this car is an AWZ P70 Zwickau Coupe (later Sachsenring), which pre-dated the more famous Trabant, and was badged as AWZ and VEB. The puzzle should therefore revert back to the Trabant P50 and continue from there IMHO, if Otto/admin agree (?). Sorry, but..!
