Folks, I am going to be in Germany in December and wanted to do a road trip Hamburg-Dusseldorf- Munich over two days.
Having done a great road trip last year on a 525d from sixt from Hamburg-Berlin-Kempten-Munich, I'd very much like to relive the pleasure of driving on the autobahn.

However not sure about weather / snow in Hamburg at that time of the year.

Would welcome opinion from those based in northern germany.

Thanks.
