Definitly use this site for planning:

The one region I would recommend is the Lakes Region of Italy near Como, Garda and Maggiore. Any of the roads around each lake has great spots.
The one road that is spectacular is from Lecco to Bellagio to Como. Very narrow and twisty with blind corners right on the water.

I' m sure EU locals will chime in. Good luck!
