I finally decided to have my Trabant checked at the the technical Inspection also for historical license Plate. Only if the car fulfills the required steps like, original state, good condition, technically ok, at least 30 years old etc. then you get the Historical Document and you can register your car as a Historical car. In the license Plate there will be a H on the right of the normal car license.
My Trabant made it :-)
I am really happy. It does not help much on the tax, because historical cars have all the same 191Euro. With the 594ccm engine I usually pay 150 Euro a year (25 Euro per 100ccm). So a Historical US Car with 7L engine would also pay 191 Euro (instead of 1750 Euro).
Anyway, I can again enter the specially dedicated environmental Cities with my Trabant.
