Guys also consider - Haute Savoie region which includes a small part of France, Switzerland and Italy around the Mont Blanc area having fabulous roads. We're just back from a great two weeks there. Car or bike - amazing.
Scotland - east, west or central anywhere above Callendar are spectacular roads .. car or bike. Even if you've never done the obvious Glencoe - it alone is worth doing - but on up Skye, Gairlock etc .. wonderful.
