Just read the info on the Bavaria meeting at the end of June. It just so happens that we were planning to go continental in the Magnette this summer, so will try & make this meeting part of the trip. It is a great part of the world. If any others from UK are thinking of going, perhaps we can liaise.
If you are concerned about blasting down the Autobahns, it is no big deal. We managed well with a motorhome towing a Smart at a steady 65-70 & didn't get in anyone's way! So no problem for a Magnette. Also as an alternative the German "Landstrasse" are very good,

even if many of them are restricted to 80kmh.
