Jack aus Maine möchte mit seiner 66er C2 Europa bereisen - Tipps?

[zuendler]

The Grossglockner is to far away from your route, so its out of choice.

You have some options coming from Germany/Austria:

Timmelsjoch (J) then to Merano then Stelvio Pass (H) and Gavia Pass (G).
But this doesn´t really fit to your suggested route with Zurich as target.

So coming from Switzerland i would drive to Torino, an then headding for
Col d Izoard © visit Col Agnel (B) and down to Cime la Bonette (A) from
where you can drive directly to Nice.

Think this takes one day from Torino to Nice.
And if you have a bit extra time you can take the Col du Galibier too this would
mean 100km more.

Google says 378km and 6:31hours from Torino to Nice if you do it that way:
