I'm from Switzerland....so from a neighbour country.
where will u be in Germany exactly?
I go sometimes to the "Schwarzwald" thats an area in the "state" "Badenwürtenberg" - a lot of twisties and a very good chance that u don't get a ticket

(don't know if u know the German speed limits and ticket fees...)
no idea about the r6 market in Germany... but I wouldn't buy ur 6 (at least not for the price I would pay for a used European one) cause the European ones have the better specs (mainly concerning electrical parts...)
